migrate from openssl to NSS

[Kaining Gu]

Hi,

I have a program that needs to do DES encryption/decryption on a
string.  It uses only two openssl functions:

    des_set_key_unchecked();
    des_ncbc_encrypt( DES_ENCRYPT or DES_DECRYPT );

Could someone please tell me what the NSS counterparts (i.e.
encrypt/decrypt a string with DES key) are?

Any help is appreciated,
Kaining
