Another trivial question: gcry_cipher_encrypt() (plaintext length)

Hi, Once more I'm demonstrating my utter lack of knowledge in all matters related to cryptography. Please forgive these trivial questions. I'm trying to use gcry_cipher_encrypt(). I've set the cipher mode to GCRY_CIPHER_MODE_CFB(*) and the algorithm is GCRY_CIPHER_AES256. My problem is that the

libgcrypt: Length of IV

Hi, Should the IV be of the same length as the key for a given symmetric cipher or can it have any length? Thanks, jules ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users

pinentry - Impossible to disable/ignore if present?

Hi, I find that pinentry unconditionally is being launched whenever I attempt to encrypt or decrypt something using gpgme. I've checked that the callback function is being set correctly using a combination of gpgme_set_passphrase_cb() and gpgme_get_passphrase_cb(). Unfortunately this is totally

gpgme_set_passphrase_cb() not working

Hi, I've written a small keyring utility(*) to store passwords and such. It is using gpgme to interface with gnupg and works wonderfully on Gentoo and Fedora. However, on OpenSUSE 10.2 it doesn't. The problem is that gpgme_set_passphrase_cb() doesn't have any effect on that platform. I'm seeing
