Deprecate the low level DES functions. Use of the low level DES functions has been informally discouraged for a long time. We now formally deprecate them. Applications should instead use the EVP APIs, e.g. EVP_EncryptInit_ex, EVP_EncryptUpdate, EVP_EncryptFinal_ex, and the equivalently named decrypt functions.

Unify DES library: ncbc_enc.c wasn't used, but its content was almost duplicated in cbc_enc.c (without IV updating) and in des_enc.c As pointed out by others on the openssl-dev list, des_cbc_encrypt (without IV updating; defined in cbc_enc.c) exists only for historical reasons: des_ncbc_encrypt should be used instead (and the caller does not have to manually update the IV). If des_cbc_enrypt is not needed for backwards compatibility, the definition of des_ncbc_encrypt should be put back into des_enc.c, and both cbc_enc.c and ncbc_enc.c can be deleted. If des_cbc_encrypt is needed for backwards compatibility, its behaviour obviously should not change (i.e., don't add IV updating). 1999-06-10 01:28:30 +08:00			`#define CBC_ENC_C__DONT_UPDATE_IV`
