- What's this?
pkcs5_keyivgen(p1, p2 = v2, p3 = v3, p4 = v4)
public
Generates and sets the key/IV based on a password.
WARNING: This method is only PKCS5 v1.5 compliant when using RC2, RC4-40, or DES with MD5 or SHA1. Using anything else (like AES) will generate the key/iv using an OpenSSL specific method. This method is deprecated and should no longer be used. Use a PKCS5 v2 key generation method from OpenSSL::PKCS5 instead.
Parameters
-
salt must be an 8 byte string if provided.
-
iterations is an integer with a default of 2048.
A minimum of 1000 iterations is recommended.
