=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 the L<pem(3)|pem(3)> manual page.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
Before using these functions L<OpenSSL_add_all_algorithms(3)|OpenSSL_add_all_algorithms(3)>
|
||
|
|
should be called to initialize the internal algorithm lookup tables otherwise errors about
|
||
|
|
unknown algorithms will occur if an attempt is made to decrypt a private key.
|
||
|
|
|
||
|
|
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)|BIO_s_mem(3)> for details.
