=head1 NAME
|
|
|
|
EVP_PKEY_CTX_set1_pbe_pass
|
|
- generic KDF support functions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/kdf.h>
|
|
|
|
int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
|
|
int passlen);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
These functions are generic support functions for all KDF algorithms.
|
|
|
|
EVP_PKEY_CTX_set1_pbe_pass() sets the password to the B<passlen> first
|
|
bytes from B<pass>.
|
|
|
|
=begin comment
|
|
|
|
We really should have a few more, such as EVP_PKEY_CTX_set1_kdf_salt,
|
|
EVP_PKEY_CTX_set1_kdf_key (to be used by the algorithms that use a
|
|
key, such as hkdf), EVP_PKEY_CTX_set1_kdf_md (same thing here).

|
=head1 STRING CTRLS
|
|
|
|
There is also support for string based control operations via
|
|
L<EVP_PKEY_CTX_ctrl_str(3)>.
|
|
The B<password> can be directly specified using the B<type> parameter
|
|
"pass" or given in hex encoding using the "hexpass" parameter.
|
|
|
|
=begin comment
|
|
|
|
Just as for the function description, the strings "salt", "hexsalt",
|
|
"key", "hexkey" and "md" should be generically specified, and
|
|
supported by the algorithms that use them.
|

|
=head1 NOTES
|
|
|
|
All these functions are implemented as macros.
|
|
|
|
=head1 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.
