172 .IX Header "DESCRIPTION"
173 The PKCS#8 functions encode and decode private keys in PKCS#8 format using both
174 PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption algorithms.
176 Other than the use of \s-1DER\s0 as opposed to \s-1PEM\s0 these functions are identical to the
177 corresponding \fB\s-1PEM\s0\fR function as described in the \fIpem\fR\|(3) manual page.
180 Before using these functions \fIOpenSSL_add_all_algorithms\fR\|(3)
181 should be called to initialize the internal algorithm lookup tables otherwise errors about
182 unknown algorithms will occur if an attempt is made to decrypt a private key.
184 These functions are currently the only way to store encrypted private keys using \s-1DER\s0 format.
186 Currently all the functions use BIOs or \s-1FILE\s0 pointers, there are no functions which
187 work directly on memory: this can be readily worked around by converting the buffers
188 to memory BIOs, see \fIBIO_s_mem\fR\|(3) for details.
