        X509_SIG *PKCS8_encrypt_ex(int pbe_nid, const EVP_CIPHER *cipher,
                                   const char *pass, int passlen, unsigned char *salt,
                                   int saltlen, int iter, PKCS8_PRIV_KEY_INFO *p8,
                                   OSSL_LIB_CTX *ctx, const char *propq);
        X509_SIG *PKCS8_set0_pbe(const char *pass, int passlen,
                                PKCS8_PRIV_KEY_INFO *p8inf, X509_ALGOR *pbe);
        X509_SIG *PKCS8_set0_pbe_ex(const char *pass, int passlen,

                                    OSSL_LIB_CTX *ctx);


DESCRIPTION

       PKCS8_encrypt() and PKCS8_encrypt_ex() perform encryption of an object
       p8 using the password pass of length passlen, salt salt of length
       saltlen and iteration count iter.  The resulting X509_SIG contains the
       encoded algorithm parameters and encrypted key.

       PKCS8_decrypt() and PKCS8_decrypt_ex() perform decryption of an
       X509_SIG in p8 using the password pass of length passlen along with
       algorithm parameters obtained from the p8.

       PKCS8_set0_pbe() and PKCS8_set0_pbe_ex() perform encryption of the
       p8inf using the password pass of length passlen and parameters pbe.

       Functions ending in _ex() allow for a library context ctx and property
       query propq to be used to select algorithm implementations.


RETURN VALUES

       PKCS8_encrypt(), PKCS8_encrypt_ex(), PKCS8_set0_pbe() and
       PKCS8_set0_pbe_ex() return an encrypted key in a X509_SIG structure or
       NULL if an error occurs.

       PKCS8_decrypt() and PKCS8_decrypt_ex() return a PKCS8_PRIV_KEY_INFO or
       NULL if an error occurs.
