.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBPKCS12_pack_p7encdata()\fR generates a PKCS#7 ContentInfo object of encrypted-data
type from the set of safeBags \fIbags\fR. The algorithm \s-1ID\s0 in \fIpbe_nid\fR can be
a PKCS#12 or PKCS#5 password based encryption algorithm, or a cipher algorithm.
If a cipher algorithm is passed, the PKCS#5 \s-1PBES2\s0 algorithm will be used with
this cipher as a parameter.
The password \fIpass\fR of length \fIpasslen\fR, salt \fIsalt\fR of length \fIsaltlen\fR
and iteration count \fIiter\fR are inputs into the encryption operation.
.PP
\&\fBPKCS12_pack_p7encdata_ex()\fR operates similar to the above but allows for a
library context \fIctx\fR and property query \fIpropq\fR to be used to select the
algorithm implementation.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
