EVP_PKEY_CTX_set1_pbe_pass - generic KDF support functions

#include <openssl/kdf.h>
int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
                               int passlen);

These functions are generic support functions for all KDF algorithms.

EVP_PKEY_CTX_set1_pbe_pass() sets the password to the passlen first bytes from pass.

There is also support for string based control operations via EVP_PKEY_CTX_ctrl_str(3). The password can be directly specified using the type parameter "pass" or given in hex encoding using the "hexpass" parameter.

All these functions return 1 for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by the public key algorithm.

EVP_PKEY_CTX_new(3), EVP_PKEY_CTX_ctrl_str(3), EVP_PKEY_derive(3)

EVP_PKEY_CTX_set1_pbe_pass() was converted from a macro to a function in OpenSSL 3.0.
