Problem with d2i functions and RSA keys in C

Hi, I'm trying to encrypt and decrypt data using RSA. In order to test, I generated a key pair using openssl rsa -outform DER and I transformed it into a C array getting this : unsigned char clepriv_der[] = { 0x30, 0x81, 0xab, 0x02, 0x01, 0x00, 0x02, 0x21, 0x00, 0xdb, 0x46, 0x81,

Re: Problem with d2i functions and RSA keys in C

Hello, clefpub=d2i_RSA_PUBKEY(NULL,(const unsigned char**)pub,62); clefpriv=d2i_RSAPrivateKey(NULL,(const unsigned char**)priv,230); puts(Chargement des clés terminé); You should check return code of this two functions, probably first function returns NULL and in RSA_check you

Hi Marek, thx for the answer This functions return : 804b298 and 804b0d0 That seems to be a pointer on a RSA object and that seems to mean that there is no error. Regards, -- Florian Manach NUMLOG [EMAIL PROTECTED] (+33)0130791616 Marek Marcola a écrit : Hello,

Hello, This functions return : 804b298 and 804b0d0 That seems to be a pointer on a RSA object and that seems to mean that there is no error. Yes, this looks good, but after looking at documentation for RSA_check_key() there is information that this function checks integrity of all

Re: Problem with d2i functions and RSA keys in C

The RSA_check_key doesn't core dump with the private key if I remove the one with the public key. I'll try to continue in this way and I'll let you know. Thanks a lot, Best regards, Marek Marcola a écrit : Hello, This functions return : 804b298 and 804b0d0 That seems to be a pointer

FIPS Module Question

Hi, I built FIPS 1.1.1, the latest 0.9.7 OpenSSL snapshot from March 2, and was able to also build the sample application mentioned in the User Guide (hmac.exe). They all work OK, but I have some questions that I can't find answers to, so I'd appreciate your help. 1. When I build OpenSSL, it

2 is not prime?

Hi, Sorry if this is a dumb question but I couldn't find the openssl bugzilla (or equivalent) to look for this. I was using openssl to check primes and kept running into these weird issues until I found this... $ openssl version OpenSSL 0.9.7f 22 Mar 2005 $ openssl prime 2 2 is not prime

Hi, $ openssl version OpenSSL 0.9.7f 22 Mar 2005 $ openssl prime 2 2 is not prime But.. 2 is prime right? correct. but its the only even prime number - hence its an odd prime number! ;-) perhaps this fact/quirk is why its not known as prime? alan
