Key size for Triple DES
843811Mar 31 2006 — edited Apr 4 2006We are using triple DES for symmetric key encryption and we specify the key size from a property file.
SYSTEM.SYM_KEY_ALGORITHM = DESede
SYSTEM.SYM_KEY_PROVIDER = BC
SYSTEM.SYM_KEY_SIZE = 192
Now triple DES uses a 168 bit key with 24 parity bits (168+24=192) , so should the key size in the property file be 168 or 192.
SYSTEM.SYM_KEY_SIZE = 168. ie, is parity bit also included as the key size
