3.5.0                                              2025-06-04                      PKCS12_ITEM_DECRYPT_D2I(3SSL)

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.

PKCS12_item_decrypt_d2i_ex() and PKCS12_item_i2d_encrypt_ex() were added in OpenSSL 3.0.

       PKCS12_item_decrypt_d2i, PKCS12_item_decrypt_d2i_ex, PKCS12_item_i2d_encrypt, PKCS12_item_i2d_encrypt_ex
       - PKCS12 item encrypt/decrypt functions

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.
