Re: Question about EVP_PKEY_decrypt() with 4K RSA key

Hi, openssl hackers! I wrote little program that demonstrates problem, see attached file. It's a bit long but it shows that only EVP_PKEY_decrypt() fails with 4K keys. Rest of functions are just fine. See evp_decrypt_with_pvtk() function for failure. 06.06.12 05:40, Dave Thompson написав(ла):

Hi. Here is a result on my Cygwin + OpenSSL 1.0.1c 10 May 2012 Reading keys...keys are ready. Encrytion/decryption with RSA-based function is OK. Encrytion/decryption with EVP-based function is OK. Signature chek is OK. It seems it works fine. Best regards, Andrey Koltsov 13.06.2012

Hi again! Andrey, thanks for testing. Seems it is platform-depended bug. My development platform is Linux, Fedora 17, x86_64 I just tested It on OpenBSD 5.0/x86, it works fine too. To OpenSSL developers: If you find my program useful as an example of EVP/PK, please feel free to publish it.

Question about EVP_PKEY_decrypt() with 4K RSA key

Hi, crypto guys! I have problem with EVP_PKEY_decrypt() function and 4K RSA private key decrypting data encrypted with EVP_PKEY_encrypt() and corresponding public key. Keys generated using openssl CA shell script. EVP_PKEY_decrypt() just returns -2 saying that this key is not supported. BUT!
