=head1 DESCRIPTION
|
||
|
|
|
||
|
|
PKCS8_encrypt() and PKCS8_encrypt_ex() perform encryption of an object I<p8> using
|
||
|
|
the password I<pass> of length I<passlen>, salt I<salt> of length I<saltlen>
|
||
|
|
and iteration count I<iter>.
|
||
|
|
The resulting B<X509_SIG> contains the encoded algorithm parameters and encrypted
|
||
|
|
key.
|
||
|
|
|
||
|
|
PKCS8_decrypt() and PKCS8_decrypt_ex() perform decryption of an B<X509_SIG> in
|
||
|
|
I<p8> using the password I<pass> of length I<passlen> along with algorithm
|
||
|
|
parameters obtained from the I<p8>.
|
||
|
|
|
||
|
|
PKCS8_set0_pbe() and PKCS8_set0_pbe_ex() perform encryption of the I<p8inf>
|
||
|
|
using the password I<pass> of length I<passlen> and parameters I<pbe>.
|
||
|
|
|
||
|
|
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
|
||
|
|
|
||
|
|
PKCS8_encrypt(), PKCS8_encrypt_ex(), PKCS8_set0_pbe() and PKCS8_set0_pbe_ex()
|
||
|
|
return an encrypted key in a B<X509_SIG> structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
PKCS8_decrypt() and PKCS8_decrypt_ex() return a B<PKCS8_PRIV_KEY_INFO> or NULL
|
||
|
|
if an error occurs.
