Field Detail DES_KEY_LENGTH final public static int DES_KEY_LENGTH(Code) Constructor Detail DESParameters public DESParameters(byte[] key)(Code) Method Detail isWeakKey public static boolean isWeakKey(byte[] key, int offset)(Code) DES has 16 weak keys. This method will check if the given DES key material is weak or semi-weak. Key material that is too short is regarded as weak. See "Applied Cryptography" by Bruce Schneier for more information. true if the given DES key material is weak or semi-weak,false otherwise. setOddParity public static void setOddParity(byte[] bytes)(Code) DES Keys use the LSB as the odd parity bit. This can be used to check for corrupt keys. Parameters:   bytes - the byte array to set the parity on.
