.SH "DESCRIPTION"
.IX Header "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.
.PP
Other than the use of \s-1DER\s0 as opposed to \s-1PEM\s0 these functions are identical to the
corresponding \fB\s-1PEM\s0\fR function as described in the \fBpem\fR\|(3) manual page.
.SH "NOTES"
.IX Header "NOTES"
Before using these functions \fBOpenSSL_add_all_algorithms\fR\|(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.
.PP
These functions are currently the only way to store encrypted private keys using \s-1DER\s0 format.
.PP
Currently all the functions use BIOs or \s-1FILE\s0 pointers, there are no functions which
work directly on memory: this can be readily worked around by converting the buffers
to memory BIOs, see \fBBIO_s_mem\fR\|(3) for details.
