DESCRIPTION
Header "DESCRIPTION" \fBPKCS12_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.
\fBPKCS12_item_i2d_encrypt() and PKCS12_item_i2d_encrypt_ex() encrypt an ASN.1
object it using the algorithm algor and password pass of length
\fIpasslen, 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
\fIpropq to be used to select algorithm implementations.
"RETURN VALUES"
Header "RETURN VALUES" \fBPKCS12_item_decrypt_d2i() and
PKCS12_item_decrypt_d2i_ex() return the decrypted
object or NULL if an error occurred.
\fBPKCS12_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.

HISTORY
Header "HISTORY" \fBPKCS12_item_decrypt_d2i_ex() and
PKCS12_item_i2d_encrypt_ex() were added in OpenSSL 3.0.
