-.B ecb_crypt(\|)
-and
-.B cbc_crypt(\|)
-implement the
-.SM NBS
-.SM DES
-(Data Encryption Standard).
-These routines are faster and more general purpose than
-.BR crypt (3).
-They also are able to utilize
-.SM DES
-hardware if it is available.
-.B ecb_crypt(\|)
-encrypts in
-.SM ECB
-(Electronic Code Book)
-mode, which encrypts blocks of data independently.
-.B cbc_crypt(\|)
-encrypts in
-.SM CBC
-(Cipher Block Chaining)
-mode, which chains together
-successive blocks.
-.SM CBC
-mode protects against insertions, deletions and
-substitutions of blocks.
-Also, regularities in the clear text will
-not appear in the cipher text.
-.LP
-Here is how to use these routines.  The first parameter,
-.IR key ,
-is the 8-byte encryption key with parity.
-To set the key's parity, which for
-.SM DES
-is in the low bit of each byte, use
-.IR des_setparity .
-The second parameter,
-.IR data ,
-contains the data to be encrypted or decrypted.
-The
-third parameter,
-.IR datalen ,
-is the length in bytes of
-.IR data ,
-which must be a multiple of 8. The fourth parameter,
-.IR mode ,
-is formed by
-.SM OR\s0'ing
-together some things.  For the encryption direction 'or' in either
-.SM DES_ENCRYPT
-or
-.SM DES_DECRYPT\s0.
-For software versus hardware
-encryption, 'or' in either
-.SM DES_HW
-or
-.SM DES_SW\s0.
-If
-.SM DES_HW
-is specified, and there is no hardware, then the encryption is performed
-in software and the routine returns
-.SM DESERR_NOHWDEVICE\s0.
-For
-.IR cbc_crypt ,
-the parameter
-.I ivec
-is the the 8-byte initialization
-vector for the chaining.  It is updated to the next initialization
-vector upon return.

-.SH DIAGNOSTICS
-.PD 0
-.TP 20
-.SM DESERR_NONE
-No error.
-.TP
-.SM DESERR_NOHWDEVICE
-Encryption succeeded, but done in software instead of the requested hardware.
-.TP
-.SM DESERR_HWERR
-An error occurred in the hardware or driver.
-.TP
-.SM DESERR_BADPARAM
-Bad parameter to routine.
-.PD
-.LP
-Given a result status
-.IR stat ,
-the macro
-.SM DES_FAILED\c
-.BR ( stat )
-is false only for the first two statuses.
-.SH RESTRICTIONS
-These routines are not available in RPCSRC 4.0.
-This information is provided to describe the DES interface expected by
-Secure RPC.
