                                         pem_password_cb *cb, void *u);

                                         char *kstr, int klen,

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 algo-
       rithms.

       Other than the use of DER as opposed to PEM these functions are identi-
       cal 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.
