Source code for the SHA512_End function.

[Oleg P.]

Hello!
Dear Developers I need a little help or advice.
Where (or how) can I find source code for the function SHA512_End in the /usr/src directory?
I need it to write a test for the 32bit implementation OpenSSL, which I began to write (https://github.com/FreeBSD-pzn/openssl_vax).

As per the man page, it says it's in libmd: https://www.freebsd.org/cgi/man.cgi...th=FreeBSD+9-current&arch=default&format=html

A further search on github of freebsd:

Build software better, together

GitHub is where people build software. More than 100 million people use GitHub to discover, fork, and contribute to over 420 million projects.

github.com

Specifically it's in:
freebsd/crypto/openssh/openbsd-compatsha2.h

The source files on your computer:
/usr/src/sys/crypto/sha2/

 

[Phishfry]

Here is the header for it:
/usr/src/sys/crypto/sha2/sha512.h

#ifndef SHA512_End
#define SHA512_End        _libmd_SHA512_End
#endif

Something related I ran across when searching:

⚙ D3929 Replace sys/crypto/sha2/sha2.c with lib/libmd/sha512c.c

reviews.freebsd.org

Here is a command to search inside all the source files for your string.
grep "SHA512_End" -rns /usr/src/

Hi!
I was trying all queries and I couldn't find source code.
The source code for the functions SHA.._End, SHA..._Data and SHA.._File are in the __attribute__(_bounded(...)), but where are all that functions?
For example: the source code for the sha512 executable file is in the md5.c.

 

[mark_j]

I'm not sure I understand?

char *SHA256_End(SHA256_CTX *, char *) __attribute__((__bounded__(__minbytes__,2,SHA256_DIGEST_STRING_LENGTH)));

This says take parameter 2 (char * - the buffer and return the SHA256_DIGEST_STRING_LENGTH (which is 129 according to the manual page):


SHA512_End() is a wrapper for SHA512_Final() which converts the return
value to a 129-character (including the terminating '\0') ASCII string
which represents the 512 bits in hexadecimal.

All the relevant functions are in sha512.c such as SHA512_Update, Sha512_Final, SHA512_Init etc.
An example of it being used:

return (SHA512_End(&(c->SHA512), buf));

(Then again it's Christmas and I may have had a few beverages...)

Hi!
I am trying to find bodies of functions SHA512_End(), SHA512_Data() and SHA512_File().
For instance: bodies of functions SHA512_Init(), SHA512_Update ... are in the sha512.c file, but
this file does not include bodies of functions SHA512_End(), SHA512_Data() and SHA512_File().

The advice is: stop wasting your time.

32bit implementation OpenSSL, which I began to write (https://github.com/FreeBSD-pzn/openssl_vax).

What makes you think OpenSSL only works with 64-bit platforms?

 

[shkhln]

Ah, so this is about OpenVMS, VAX and compiler support for long long / int64_t. That's completely off-topic here.

Issue has nothing to do with FreeBSD. Thread closed.
