.SH DESCRIPTION
.IX Header "DESCRIPTION"
All of the functions described on this page are deprecated.
Applications should instead use \fBEVP_PKEY_print_params\fR\|(3) and
\&\fBEVP_PKEY_print_private\fR\|(3).
.PP
A human-readable hexadecimal output of the components of the RSA
key, DSA parameters or key or DH parameters is printed to \fBbp\fR or \fBfp\fR.
.PP
The output lines are indented by \fBoffset\fR spaces.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBDSAparams_print()\fR, \fBDSAparams_print_fp()\fR, \fBDSA_print()\fR, and \fBDSA_print_fp()\fR
return 1 for success and 0 or a negative value for failure.
.PP
\&\fBDHparams_print()\fR and \fBDHparams_print_fp()\fR return 1 on success, 0 on error.
