68 | .Sh DESCRIPTION | ||
69 | The PKCS#8 functions encode and decode private keys in PKCS#8 format | ||
70 | using both PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption | ||
71 | algorithms. | ||
72 | .Pp | ||
73 | Other than the use of DER as opposed to PEM these functions are | ||
74 | identical to the corresponding | ||
75 | .Xr pem 3 | ||
76 | functions. | ||
77 | .Sh NOTES | ||
78 | Before using these functions, | ||
79 | .Xr OpenSSL_add_all_algorithms 3 | ||
80 | should be called to initialize the internal algorithm lookup tables. | ||
81 | Otherwise errors about unknown algorithms will occur if an attempt is | ||
82 | made to decrypt a private key. | ||
83 | .Pp | ||
84 | These functions are currently the only way to store encrypted private | ||
85 | keys using DER format. | ||
86 | .Pp | ||
87 | Currently all the functions use | ||
88 | .Vt BIO | ||
89 | or | ||
90 | .Vt FILE | ||
91 | pointers, there are no functions which work directly on memory: | ||
92 | this can be readily worked around by converting the buffers to | ||
93 | memory BIOs, see | ||
94 | .Xr BIO_s_mem 3 | ||
95 | for details. | ||
