- * Synopsis: desinit(key)
- * Description: intializes all arrays and permutation tables for
- * single DES
- * Input: key - 64-bit DES key
- * Output: 0 if OK; >0 if a (semi) weak was selected
- *
- * Synopsis: des3init(key)
- * Description: intializes all arrays and permutation tables for
- * triple DES
- * Input: key - 128-bit DES key
- * Output: 0 if OK; >0 if a (semi) weak was selected
- *
- * Synopsis: ecbXcode(inblock,outblock)
- * Description: encrypts (X=en) or decrypts (X=de) 64-bit inblock to
- * 64-bit outblock using single DES in ECB mode
- * Input: inblock - pointer to 64-bit buffer of input data
- * outblock - pointer to 64-bit buffer for output data
- * Output: 0 if OK

- * Input: inblock - pointer to 64-bit buffer of input data
- * outblock - pointer to 64-bit buffer for output data
- * ivec - pointer to 64-bit initilization vector
- * Output: 0 if OK
