errno = 2 after gcry_cipher_open

[Jesús Díaz Vico]

Hello everybody,

I'm new to libgcrypt. I'm trying to cipher some data with ARCFOUR, but, just after calling gcry_cipher_open I get errno = 2. The weird thing is that gcry_cipher_open returns
no error (i.e., gcry_error_t == GPG_ERR_NO_ERROR). I'm getting mad trying to find where the problem is. 

The way I'm calling gcry_cipher is: 

gcry_cipher_open(&chd, GCRY_CIPHER_ARCFOUR, GCRY_CIPHER_MODE_STREAM, GCRY_CIPHER_SECURE);

Where chd is a local variable, declared as gcry_cipher_hd_t, within the function which calls gcry_cipher_open. I've also tried without GCRY_CIPHER_SECURE.

I've compared my code to the check_one_cipher fucntion that tests the algorithms and everything seems the same. Also, I did not had any problem during libgcrypt installation (make check did pass every test).

Could anybody please give me any hint?

Thank you.
