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.
