DESCRIPTION
       PKCS12_item_decrypt_d2i() and PKCS12_item_decrypt_d2i_ex() decrypt an
       octet string containing an ASN.1 encoded object using the algorithm
       algor and password pass of length passlen. If 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 it using the algorithm algor and password pass of length
       passlen, returning an encoded object in obj. If 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 ctx and property
       query propq to be used to select algorithm implementations.

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.
