164 .IX Header "DESCRIPTION"
165 The PKCS#8 functions encode and decode private keys in PKCS#8 format using both
166 PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption algorithms.
168 Other than the use of \s-1DER\s0 as opposed to \s-1PEM\s0 these functions are identical to the
169 corresponding \fB\s-1PEM\s0\fR function as described in \fIPEM_read_PrivateKey\fR\|(3).
172 These functions are currently the only way to store encrypted private keys using \s-1DER\s0 format.
174 Currently all the functions use BIOs or \s-1FILE\s0 pointers, there are no functions which
175 work directly on memory: this can be readily worked around by converting the buffers
176 to memory BIOs, see \fIBIO_s_mem\fR\|(3) for details.
178 These functions make no assumption regarding the pass phrase received from the
180 It will simply be treated as a byte sequence.
182 .IX Header "RETURN VALUES"
183 \&\fId2i_PKCS8PrivateKey_bio()\fR and \fId2i_PKCS8PrivateKey_fp()\fR return a valid \fB\s-1EVP_PKEY\s0\fR
184 structure or \s-1NULL\s0 if an error occurred.
186 \&\fIi2d_PKCS8PrivateKey_bio()\fR, \fIi2d_PKCS8PrivateKey_fp()\fR, \fIi2d_PKCS8PrivateKey_nid_bio()\fR
187 and \fIi2d_PKCS8PrivateKey_nid_fp()\fR return 1 on success or 0 on error.
