=head1 DESCRIPTION
|
|
|
|
PKCS12_PBE_keyivgen() and PKCS12_PBE_keyivgen_ex() take a password I<pass> of
|
|
length I<passlen>, parameters I<param> and a message digest function I<md_type>
|
|
and perform a key derivation according to PKCS#12. The resulting key is
|
|
then used to initialise the cipher context I<ctx> with a cipher I<cipher> for
|
|
encryption (I<en_de>=1) or decryption (I<en_de>=0).
|
|
|
|
PKCS12_PBE_keyivgen_ex() also allows the application to specify a library context
|
|
I<libctx> and property query I<propq> to select appropriate algorithm
|
|
implementations.
|
|
|
|
PKCS12_pbe_crypt() and PKCS12_pbe_crypt_ex() will encrypt or decrypt a buffer
|
|
based on the algorithm in I<algor> and password I<pass> of length I<passlen>.
|
|
The input is from I<in> of length I<inlen> and output is into a malloc'd buffer
|
|
returned in I<*data> of length I<datalen>. The operation is determined by I<en_de>,
|
|
encryption (I<en_de>=1) or decryption (I<en_de>=0).
|
|
|
|
PKCS12_pbe_crypt_ex() allows the application to specify a library context
|
|
I<libctx> and property query I<propq> to select appropriate algorithm
|
|
implementations.
|
|
|
|
I<pass> is the password used in the derivation of length I<passlen>. I<pass>
|
|
is an optional parameter and can be NULL. If I<passlen> is -1, then the
|
|
function will calculate the length of I<pass> using strlen().
|
|
|
|
I<salt> is the salt used in the derivation of length I<saltlen>. If the
|
|
I<salt> is NULL, then I<saltlen> must be 0. The function will not
|
|
attempt to calculate the length of the I<salt> because it is not assumed to
|
|
be NULL terminated.
|
|
|
|
I<iter> is the iteration count and its value should be greater than or
|
|
equal to 1. RFC 2898 suggests an iteration count of at least 1000. Any
|
|
I<iter> less than 1 is treated as a single iteration.
|
|
|
|
I<digest> is the message digest function used in the derivation.
|
|
|
|
Functions ending in _ex() take optional parameters I<libctx> and I<propq> which
|
|
are used to select appropriate algorithm implementations.
|
|
|
|
=head1 NOTES
|
|
|
|
The functions are typically used in PKCS#12 to encrypt objects.
|
|
|
|
These functions make no assumption regarding the given password.
|
|
It will simply be treated as a byte sequence.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
PKCS12_PBE_keyivgen(), PKCS12_PBE_keyivgen_ex() return 1 on success or 0 on error.
|
|
|
|
PKCS12_pbe_crypt() and PKCS12_pbe_crypt_ex() return a buffer containing the
|
|
output or NULL if an error occurred.
