.SH NAME
EVP_PKEY_CTX_set1_pbe_pass
\&\- generic KDF support functions
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/kdf.h>
\&
\& int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
\&                                int passlen);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
These functions are generic support functions for all KDF algorithms.
.PP
\&\fBEVP_PKEY_CTX_set1_pbe_pass()\fR sets the password to the \fBpasslen\fR first
bytes from \fBpass\fR.
.SH "STRING CTRLS"
.IX Header "STRING CTRLS"
There is also support for string based control operations via
\&\fBEVP_PKEY_CTX_ctrl_str\fR\|(3).
The \fBpassword\fR can be directly specified using the \fBtype\fR parameter
"pass" or given in hex encoding using the "hexpass" parameter.
.SH "RETURN VALUES"
.IX Header "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.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
\&\fBEVP_PKEY_CTX_new\fR\|(3),
\&\fBEVP_PKEY_CTX_ctrl_str\fR\|(3),
\&\fBEVP_PKEY_derive\fR\|(3)
.SH HISTORY
.IX Header "HISTORY"
\&\fBEVP_PKEY_CTX_set1_pbe_pass()\fR was converted from a macro to a function in
OpenSSL 3.0.
