encrypt/decrypt functions
=head1 SYNOPSIS

void *PKCS12_item_decrypt_d2i(const X509_ALGOR *algor, const ASN1_ITEM *it,
const char *pass, int passlen,
const ASN1_OCTET_STRING *oct, int zbuf);

ASN1_OCTET_STRING *PKCS12_item_i2d_encrypt(X509_ALGOR *algor,
const ASN1_ITEM *it,
const char *pass, int passlen,

ASN1_OCTET_STRING *PKCS12_item_i2d_encrypt_ex(X509_ALGOR *algor,

=head1 DESCRIPTION
PKCS12_item_decrypt_d2i() and PKCS12_item_decrypt_d2i_ex() decrypt an octet
string containing an ASN.1 encoded object using the algorithm I<algor> and
password I<pass> of length I<passlen>. If I<zbuf> is nonzero then the output
buffer will zeroed after the decrypt.
PKCS12_item_i2d_encrypt() and PKCS12_item_i2d_encrypt_ex() encrypt an ASN.1
object I<it> using the algorithm I<algor> and password I<pass> of length
I<passlen>, returning an encoded object in I<obj>. If I<zbuf> is nonzero then
the buffer containing the input encoding will be zeroed after the encrypt.
Functions ending in _ex() allow for a library context I<ctx> and property query
I<propq> to be used to select algorithm implementations.
=head1 RETURN VALUES
PKCS12_item_decrypt_d2i() and PKCS12_item_decrypt_d2i_ex() return the decrypted
object or NULL if an error occurred.
PKCS12_item_i2d_encrypt() and PKCS12_item_i2d_encrypt_ex() return the encrypted
data as an ASN.1 Octet String or NULL if an error occurred.

L<PKCS8_encrypt_ex(3)>
=head1 HISTORY
PKCS12_item_decrypt_d2i_ex() and PKCS12_item_i2d_encrypt_ex() were added in OpenSSL 3.0.
