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.
