.SH "DESCRIPTION"

\&\fBPKCS12_item_decrypt_d2i()\fR and \fBPKCS12_item_decrypt_d2i_ex()\fR decrypt an octet
string containing an \s-1ASN.1\s0 encoded object using the algorithm \fIalgor\fR and
password \fIpass\fR of length \fIpasslen\fR. If \fIzbuf\fR is nonzero then the output
buffer will zeroed after the decrypt.
.PP
\&\fBPKCS12_item_i2d_encrypt()\fR and \fBPKCS12_item_i2d_encrypt_ex()\fR encrypt an \s-1ASN.1\s0
object \fIit\fR using the algorithm \fIalgor\fR and password \fIpass\fR of length
\&\fIpasslen\fR, returning an encoded object in \fIobj\fR. If \fIzbuf\fR is nonzero then
the buffer containing the input encoding will be zeroed after the encrypt.
.PP
Functions ending in \fB_ex()\fR allow for a library context \fIctx\fR and property query
\&\fIpropq\fR to be used to select algorithm implementations.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBPKCS12_item_decrypt_d2i()\fR and \fBPKCS12_item_decrypt_d2i_ex()\fR return the decrypted
object or \s-1NULL\s0 if an error occurred.
.PP
\&\fBPKCS12_item_i2d_encrypt()\fR and \fBPKCS12_item_i2d_encrypt_ex()\fR return the encrypted
data as an \s-1ASN.1\s0 Octet String or \s-1NULL\s0 if an error occurred.
