64 bit DES CryptoSystem, encryption Software. DESCryptoSystem is a DATA ENCRYPTION STANDARD cryptosystem basicly known as DES. It is a symetrical key system with 64 bit Key length good enough for bulk encryption of text Files. A key can be generated and stored in a keystore, which can then be retreived and used in future. If you need to encrypt vast ammounts of data use this instead of RSA1024Cryptosystem, also found on this site. A password allows you to store the key and retreive later from persistence key store.
