EVP_KDF-PBKDF1 - The PBKDF1 EVP_KDF implementation
Support for computing the PBKDF1 password-based KDF through the EVP_KDF API.
The EVP_KDF-PBKDF1 algorithm implements the PBKDF1 password-based key derivation function, as described in RFC 8018; it derives a key from a password using a salt and iteration count.
PBKDF1 is the name for this implementation; it can be used with the EVP_KDF_fetch() function.
The supported parameters are:
This parameter has a default value of 0 and should be set.
These parameters work as described in PARAMETERS in EVP_KDF (3).
A typical application of this algorithm is to derive keying material for an encryption algorithm from a password in the pass, a salt in salt, and an iteration count.
Increasing the iter parameter slows down the algorithm which makes it harder for an attacker to perform a brute force attack using a large number of candidate passwords.
No assumption is made regarding the given password; it is simply treated as a byte sequence.
