NAME

       EVP_PKEY_CTX_set1_pbe_pass - generic KDF support functions

SYNOPSIS

        #include <openssl/kdf.h>

        int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
                                       int passlen);

DESCRIPTION

       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.

STRING CTRLS

       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.

NOTES

       All these functions are implemented as macros.

RETURN VALUES

       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.
