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
PEM function as described in the
pem(3) manual
page.
NOTES¶
Before using these functions
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
BIO_s_mem(3) for details.
