Re: [MSEide-MSEgui-talk] Is it possible to produce SHA256 digest with MSEgui ?
I see You've implemented the digest handler, great thanx !
A wish: convinience trascoding functions for string in-out data as
tcustomcryptohandler does with its [de]crypt[text] so that avoid
dealing with the heavy tmsefilestream for such small tasks.

Next is a zlib handler. And smth capable of multiple files at once and maintaining directory structures ? zlib == BTW,it's buggy in FPC - it hangs in win9x for some reason (in the ROZNITSA, me had to disable backing up data in win-98).

No. Really, It can be achieved by processing std(in/out) of the TAR archiver provided that one can issue/absorb TStream. 2012/7/7, Martin Schreiber mse00...@gmail.com: On Saturday 07 July 2012 17:10:57 Ivanko B wrote: Next is a zlib handler.

Like echo qwerty -n | sha256sum | awk '{print $1}' or echo -n qwerty |
openssl dgst -sha256 do.

Not yet. Use the EVP_Digest*() functions.
From the OPENSL docs:
//-
New applications should use the SHA2 digest algorithms such as SHA256. The
other digest algorithms are still in common use.
For most applications the impl parameter to EVP_DigestInit_ex() will be
set to NULL to use the default digest implementation.
The functions EVP_DigestInit(), EVP_DigestFinal() and EVP_MD_CTX_copy()
are obsolete but are retained to maintain compatibility with existing
code. New applications should use EVP_DigestInit_ex(),
EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex() because they can efficiently
reuse a digest context instead of initializing and cleaning it up on each
call and allow non default implementations of digests to be specified.
In OpenSSL 0.9.7 and later if digest contexts are not cleaned up after
use memory leaks will occur.
