       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 PEM_read_PrivateKey(3).


       These functions are currently the only way to store encrypted private keys using DER

       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.

       These functions make no assumption regarding the pass phrase received from the password
       callback.  It will simply be treated as a byte sequence.


       d2i_PKCS8PrivateKey_bio() and d2i_PKCS8PrivateKey_fp() return a valid EVP_PKEY structure
       or NULL if an error occurred.

       i2d_PKCS8PrivateKey_bio(), i2d_PKCS8PrivateKey_fp(), i2d_PKCS8PrivateKey_nid_bio() and
       i2d_PKCS8PrivateKey_nid_fp() return 1 on success or 0 on error.
