+=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.
