Currently, I am attempting to generating a hash of a user password for PDF, given the encrypted PDF file and the plain password. I follow the instruction of this article. However, the hash I've computed is different from the hash stored in the PDF file.
The hashed user password (/U entry) is simply the 32-byte padding
string above, encrypted with RC4, using the 5-byte file key. Compliant
PDF viewers will check the password given by the user (by attempting
to decrypt the /U entry using the file key, and comparing it against
the padding string) and allow or refuse certain operations based on
the permission settings.
First, I padded my password "123456" using a hardcoded 32-byte string, which gives me
31 32 33 34 35 36 28 BF 4E 5E 4E 75 8A 41 64 00
4E 56 FF FA 01 08 2E 2E 00 B6 D0 68 3E 80 2F 0C
I tried to compute the hash with RC4 using the 5-byte file key as the key. According to the article:
The encryption key is generated as follows:
1. Pad the user password out to 32 bytes, using a hardcoded
32-byte string:
28 BF 4E 5E 4E 75 8A 41 64 00 4E 56 FF FA 01 08
2E 2E 00 B6 D0 68 3E 80 2F 0C A9 FE 64 53 69 7A
If the user password is null, just use the entire padding
string. (I.e., concatenate the user password and the padding
string and take the first 32 bytes.)
2. Append the hashed owner password (the /O entry above).
3. Append the permissions (the /P entry), treated as a four-byte
integer, LSB first.
4. Append the file identifier (the /ID entry from the trailer
dictionary). This is an arbitrary string of bytes; Adobe
recommends that it be generated by MD5 hashing various pieces
of information about the document.
5. MD5 hash this string; the first 5 bytes of output are the
encryption key. (This is a 40-bit key, presumably to meet US
export regulations.)
I appended the hashed owner key to the padded password, which gives me
31 32 33 34 35 36 28 BF 4E 5E 4E 75 8A 41 64 00
4E 56 FF FA 01 08 2E 2E 00 B6 D0 68 3E 80 2F 0C
C4 31 FA B9 CC 5E F7 B5 9C 24 4B 61 B7 45 F7 1A
C5 BA 42 7B 1B 91 02 DA 46 8E 77 12 7F 1E 69 D6
Then, I appended the /P entry (-4), treated as a four-byte integer, encoded with little endian, which gives me
31 32 33 34 35 36 28 BF 4E 5E 4E 75 8A 41 64 00
4E 56 FF FA 01 08 2E 2E 00 B6 D0 68 3E 80 2F 0C

C5 BA 42 7B 1B 91 02 DA 46 8E 77 12 7F 1E 69 D6
FC FF FF FF
Last, I appended the file identifier to it. The trailer of my PDF is:
trailer
<<
/Size 13
/Root 2 0 R
/Encrypt 1 0 R
/Info 4 0 R
/ID [<B5185D941CC0EA39ACA809F661EF36D4> <393BE725532F9158DC9E6E8EA97CFBF0>]
>>
and the result is
31 32 33 34 35 36 28 BF 4E 5E 4E 75 8A 41 64 00
4E 56 FF FA 01 08 2E 2E 00 B6 D0 68 3E 80 2F 0C

MD5 hashing this block of data returns 942c5e7b2020ce57ce4408f531a65019. I RC4-ed the padded password with cryptii using the first 5 bytes of the MD5 hash as the key. However, it returns
90 e2 b5 21 2a 7d 53 05 70 d9 5d 26 95 c7 c2 05
6e 2a 28 40 63 e7 4a d4 e9 05 86 71 43 d1 39 d6
while the hash in PDF is
58 81 CA 74 65 DC 2E A7 5D D2 39 D4 43 9C 0D DE
28 BF 4E 5E 4E 75 8A 41 64 00 4E 56 FF FA 01 08
Which step am I doing wrong? I suspect that the problem happens because
I am appending the File Idenifier in a wrong format
I am using the wrong drop bytes with RC4.
The hash function is not for PDF 1.6
I make some mistake during those process
Or maybe the article is actually wrong

Please help
There are two issues in your calculation:
The article to use refers to PDF encryption algorithms available for PDF-1.3 but your document is encrypted using an algorithm introduced with PDF-1.5.
You make an error when appending the file identifier - actually only the first entry of the ID array shall be appended, not both (which is not really clear from the article you use).
In a comment you asked accordingly
where can I find the password hashing detail for >V1.3 PDF?
I would propose using the PDF specification, ISO 32000.
As ISO specifications go, they are not free, but Adobe used to provide a version of ISO 32000-1 with merely the ISO header removed on their web site. Some days ago it has been removed (By design? By error? I don't know yet.) but you still find copies of it googl'ing for "PDF32000".
The relevant section in ISO 32000-1 is 7.6 Encryption and in particular 7.6.3 Standard Security Handler.
Following that information you should be able to correctly calculate the value in question.
(Alternatively you can also use old Adobe PDF references, the editions for PDF 1.5, 1.6, and 1.7 should also give you the information required for decrypting your document. But these references have been characterized as not normative in nature by prominent Adobe employees, so I would go for the ISO norm.)
Beware, though: After ISO 32000-1 had been published, Adobe introduced an AES-256 encryption scheme as an extension which obviously is not included in ISO 32000-1. You can find a specification in "Adobe Supplement to ISO 32000, base version 1.7, extension level 3".
Furthermore, with ISO 32000-2 that Adobe AES-256 encryption scheme and all older schemes became deprecated, the only encryption scheme to use with PDF-2.0 is a new AES-256 encryption scheme described in ISO 32000-2 which is based on the Adobe scheme but introduces some extra hashing iterations.
I am trying to debug the SSL connection of a client I do not have control over.
A possibility I discovered is to use openssl as a server to check whether the SSL connection is correctly initiated, and if not - why.
The basic connection ends with
root#elk:~# openssl s_server -key sonoff.key -cert sonoff.crt -accept 5555 -www
Using default temp DH parameters
ACCEPT
bad gethostbyaddr
140612029986456:error:140780E5:SSL routines:ssl23_read:ssl handshake failure:s23_lib.c:137:
What does this error actually mean?
The searches I did point to various bugs, but they all gravitate around "incorrect certificates". The certificates I use are correct, although self-signed. What in the message (or the -debug version below) could suggest this? Specifically: could this be an indication of the device checking the certificate and aborting on a self-signed?
root#elk:~# openssl s_server -key sonoff.key -cert sonoff.crt -accept 5555 -www -debug

What does this error actually mean?
At the risk of stating the obvious it literally means "the handshake failed" and doesn't give you any more information than that. It could be caused by any number of possible issues. From your debug output we can see that:
The client issues a ClientHello to the server
The server responds with a ServerHello, a Certificate and a ServerHelloDone.
The server then attempts to read a response from the client but this read fails (most probably because the client has aborted - but without sending any kind of alert to indicate the cause of the problem).
Clearly something in the response that your server has sent back to the client has caused the client to just give up. The most likely culprit is the certificate, but its also possible that there is something about the ServerHello it doesn't like (e.g. the server didn't understand some extension that the client sent in its ClientHello, which it refuses to work without...although this is quite unlikely)
When looking in details to your debug log, it looks like a normal client/server handshake, in TLS 1.2. The last 9 bytes written mean the SERVER HELLO DONE is accomplished, and then the client (the last "read from") is sending 5 bytes that unfortunately we don't have. 5 bytes is a normal thing at this moment, these bytes are supposed to continue with the TLS exchange (Client key exchange,..) and they contain the "hello" byte, the protocol version (2 bytes), and the data length (2 bytes).
All this work would be easier for me if you provided a network capture. But OK, we have some information.
There is one reason to make openssl bug at this moment, when we receive 5 bytes instead of 11. This code will later generate the same handshake failure that you get :
* Request this many bytes in initial read.
* We can detect SSL 3.0/TLS 1.0 Client Hellos
* ('type == 3') correctly only when the following
* is in a single record, which is not guaranteed by
* the protocol specification:
* Byte Content
* 0 type \
* 1/2 version > record header
* 3/4 length /
* 5 msg_type \
* 6-8 length > Client Hello message
* 9/10 client_version /
*/
char buf_space[11];
But without any capture, it's almost impossible to say whether the client is sending a wrong Client key exchange, or if it's your openssl version which is faulty (more likely, it's the client).
Can you check what openssl version you are running ?
This appears to be a network or stack problem.
Assuming we are the server at 10.200.0.13 and the client is 10.100.10.113 your network dump decodes as follows:
18:19:07,529,418 receive connect request (SYN) from port 22695 to port 5555 with starting seq 0x0036bfc5
18:19:07,529,450 send accept (SYN ACK) with starting seq 0x6261d46d
18:19:07,668,343 receive segment containing ClientHello message with seq 0x0036bfc6 len 0x54
18:19:07,668,359 send ack (through 0x0036c01a)
18:19:07,668,617 send segment containing ServerHello, Certificate, ServerHelloDone with seq 0x6261d46e len 0x56+0x512+9=0x571
18:19:08,150,907 after no response ~0.5s, resend segment
18:19:08,556,603 receive resend of client 0x0036bfc6, which does NOT ack our data;
this implies client didn't get our data-ack and didn't get or accept (either copy of) our 0x6261d46e
18:19:08,556,617 send probe (ACK with no additional data)
18:19:08,683,863 receive probe from client, again neg-acking data but pos-acking SYN
18:19:08,683,932 after 2x neg-ack, send FIN (seq 0x6261d9df)
18:19:08,762,143 receive ACK of our FIN (and data?) (ack=0x6261d9e0)
18:19:16,784,169 receive new connect (SYN) from port 6192
...
This is screwy. If the client is any normal computer with an OS, usually those ack data at TCP level in the protocol stack even if their user program doesn't read (or accept) the data, at least up to some reasonable buffersize. The client is clearly getting at least some of our frames, since it correctly acks SYN and FIN, but it apparently refuses to ack our data.
If the client is something like a thermostat or an Arduino, where there is no actual OS but often instead a heap of code someone mashed together, often by copying from websites (including Stack?) without understanding it, so it doesn't work right. Or possibly the actual client is correct, but there is some broken middlebox like a firewall, IDS, 'smart' router, etc. in between.
Anyway if you can't get the TLS protocol messages, which are TCP data, delivered to the client at the TCP level, nothing else can work, so without any more useful info about or control over the client you're out of luck.
Sorry.

A reverse DNS is not working well on your server. With your server IP, run these commands and check if they return anything (I suppose you're on Linux) :
dig -x XXX.XXX.XXX.XXX
host XXX.XXX.XXX.XXX
Check that your hosts file solves correctly your hostname. If you have to configure a DNS server (/etc/resolv.conf), do it.
My application is using SSL over SMTP.
But I faced a problem of extra byte at the end.

The length of this packet as seen from SSL 3.1 protocol is 256 Bytes.
But there is one extra byte at the end (shown in bold at the end).
Due to this extra byte at the end, when next packet is being read, then this 20 is also read and causes error of SSL_R_WRONG_VERSION_NUMBER (I am using OpenSSL Library for SSL).
Next packet which I recieved is like (as per packet sniffer)
17 03 01 00 18 ...
But when next read is being done, OpenSSL reads packet as 20 17 03 01 .. which causes the error (since 17 03 is wrong version for 03 01)
I would like to know if this (extra byte at the end) is a part of SSL standard.
Please suggest me how to handle this case in OpenSSL. OpenSSL version is 1.0.0.
No. The extra byte is not as a part of SSL Standard.
As per SSL Standard (RFC 2246 for TLS 1.0, Latest is RFC 5246 for TLS 1.2) the record of SSL is as below:
struct {
ContentType type;
ProtocolVersion version;
uint16 length;
select (CipherSpec.cipher_type) {
case stream: GenericStreamCipher;
case block: GenericBlockCipher;
} fragment;
} TLSCiphertext;
The fragment will be exactly of the length as specified by uint16 length member. So, the 20 must be getting inserted either incorrectly by the Server Implementation, or some other software in the middle is inserting it when the data is in network.
Openssl reads exactly the number of bytes as specified by uint16 length member which is why it doesn't read 20.
Some of the points which you can focus on are:
1. Does this happen with the first application data packet which is transferred immediately after handshake? (From the content type I assumed this packet dump is for application data)
2. Is this a random occurance? Do all connections with that particular server exhibit the same behavior?
3. You can try to get the dump of the packet sent at the Server to see if 20 is present when the packet is being sent at the Server side itself or it is getting added during it's flight.
4. Could there be a Firewall related problem? (I don't know about Firewall, so didn't give more details here)
Hope this helps!
I was bashing my head with this one today; finally resorted to this:
_sslStream.Write(merged, 0, merged.Length - 1)
Problem solved, move along!

The entire file seems to be there, and I can get the text.
I'd like to get back the plain CSS file somehow. I tried extracting the data, but gzip says it isn't gzip format. But it doesn't seem to be gzip encoded (it's not binary, after all...). Is it base64 or something? I've had a hard time finding any info on this.
Try finding the gzip header by extracting the hex data into an editor and searching for the header as per gzip specification. You should be able to do this by finding the end of the response body and selecting the previous 7588 bytes (you have this info in the response headers: Content-Length: 7588) - this should be the first character of the header.
Depending on the flags set in the header, gzip'd files may be ASCII or binary. You can determine if data are base64 encoded as base64 scheme encodings terminate with the = character. You can decode base64 online.
Alternatively you could try a tool such as ChromeCacheViewer.
The file looks gzip. It has the 1f8b header. Chrome stores the cached files as files, you just need to find them. Google for "location of chrome cache" and find it for your platform.

Does anyone know the SSH key file format?
!! UPDATE
!! The base64 function I was using doesn't work. After running the key file through a different function (mozilla's built in atob()) the data fit into the specifications listed above.
I have rsa key files created with puttygen, but I must be missing something critical. Here is the hex of the public section:
00 00 00 07 73 73 68 2d 72 73 61 00 00 00 01 25
00 00 00 10 1c 1c 57 3f 4f 58 63 69 38 ad 19 35
b5 28 3d 78 53 35 53 6c 15 0e 69 23 ac 17 14 84
21 29 13 07 36 62 90 26 37 93 73 17 28 b8 ce 95
c3 11 24 21 61 b7 82 d9 04 42 97 f8 27 c3 44 06
46 ca e8 a3 a3 34 d7 3c c3 95 13 dd 16 1b 2c 29
7c 35 19 5f c2 7a 17 d5 14 0d 26 36 27 18 71 67
8d 9c 5b c4 7d
first 4 bytes are UINT 7, the number of bytes inthe following string "ssh-rsa" but the format stops making sense after that. It SHOULD be followed by two MPINT but they lengths don't add up for the 3rd value.
Thanks!
It's in ASN.1 syntax. You should be able to use an ASN.1 parser along with the specs for the file contents to decipher it.
