Re[2]: [openssl.org #748] bug in speed.c
Hello Lutz,
It's me again :)
bug in speed.c:
insead
#ifndef OPENSSL_NO_DSA
if (strcmp(*argv,dsa) == 0)
{
dsa_doit[R_DSA_512]=1;
dsa_doit[R_DSA_1024]=1;
}
else
probably must be
#ifndef OPENSSL_NO_DSA
if (strcmp(*argv,dsa) == 0)
{
dsa_doit[R_DSA_512]=1;
dsa_doit[R_DSA_1024]=1;
dsa_doit[R_DSA_2048]=1;
}
else
dsa is equal dsa512 dsa1024 dsa2048 ?

The block cipher algorithms do work in memory. It is however not necessary that the data to be handled is a power of 2. It just has to be a multiple of the block size. For DES, it can be 8, 16, 24, 32, etc. (padding is required to reach the full multiple). The algorithms themselves do work in memory, so if you have data too large to be held in memory, you have to work in chunks. In CBC (cipher block chaining mode), the IV (initial value) coming out of the last crypto operation has to be used as the starting point for the next one.

Re: [openssl.org #748] bug in speed.c
Hello Lutz, Last month I try find answer for: What block (I mean what are long the block) is standard for cbc's like des/idea/aes and using in SSH/SSL and other well known applications? openssl speed dive me too many results and I want to choose major. Can You help me? -- Best regards, Kirillmailto:[EMAIL PROTECTED] __ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]

Hello Lutz, seems to be I find answer :) type/block size in openssl speed is just buffer size for calling cbc routines. and block size is fixed for different algorithms (as 8 bytes for DES). but now I don't clear about type. Is it simply input data size and can be not only 16,64,256,1024,8192 bytes and even more? and openssl can work with files not only in memory and they can be any size? -- Best regards, Kirillmailto:[EMAIL PROTECTED] __ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]

[EMAIL PROTECTED] - Wed Oct 29 08:34:31 2003]: Hello! It's me agaig :) I change speed.c for benchmarking AES methods too. It was easy :) May be it will help you. Thanks, I have applied your changes to CVS. Best regards, Lutz __ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
