34 The PKCS#8 functions encode and decode private keys in PKCS#8 format using both
35 PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption algorithms.
37 Other than the use of DER as opposed to PEM these functions are identical to the
38 corresponding B<PEM> function as described in the L<pem(3)|pem(3)> manual page.
42 Before using these functions L<OpenSSL_add_all_algorithms(3)|OpenSSL_add_all_algorithms(3)>
43 should be called to initialize the internal algorithm lookup tables otherwise errors about
44 unknown algorithms will occur if an attempt is made to decrypt a private key.
46 These functions are currently the only way to store encrypted private keys using DER format.
48 Currently all the functions use BIOs or FILE pointers, there are no functions which
49 work directly on memory: this can be readily worked around by converting the buffers
50 to memory BIOs, see L<BIO_s_mem(3)|BIO_s_mem(3)> for details.
