=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The PKCS#8 functions encode and decode private keys in PKCS#8 format using both
|
||
|
|
PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption algorithms.
|
||
|
|
|
||
|
|
Other than the use of DER as opposed to PEM these functions are identical to the
|
||
|
|
corresponding B<PEM> function as described in L<PEM_read_PrivateKey(3)>.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
These functions are currently the only way to store encrypted private keys using DER format.
|
||
|
|
|
||
|
|
Currently all the functions use BIOs or FILE pointers, there are no functions which
|
||
|
|
work directly on memory: this can be readily worked around by converting the buffers
|
||
|
|
to memory BIOs, see L<BIO_s_mem(3)> for details.
|
||
|
|
|
||
|
|
These functions make no assumption regarding the pass phrase received from the
|
||
|
|
password callback.
|
||
|
|
It will simply be treated as a byte sequence.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
d2i_PKCS8PrivateKey_bio() and d2i_PKCS8PrivateKey_fp() return a valid B<EVP_PKEY>
|
||
|
|
structure or NULL if an error occurred.
|
||
|
|
|
||
|
|
i2d_PKCS8PrivateKey_bio(), i2d_PKCS8PrivateKey_fp(), i2d_PKCS8PrivateKey_nid_bio()
|
||
|
|
and i2d_PKCS8PrivateKey_nid_fp() return 1 on success or 0 on error.
