SSCP · Question #1075
DES - Data Encryption standard has a 128 bit key and is very difficult to break.
The correct answer is B. False. The statement is false because the Data Encryption Standard (DES) uses a 56-bit key, not a 128-bit key, and it is considered insecure and easily breakable by modern computational standards.

Why each option
The statement is false because the Data Encryption Standard (DES) uses a 56-bit key, not a 128-bit key, and it is considered insecure and easily breakable by modern computational standards.
The statement is false; DES uses a 56-bit key and is easily breakable with modern computing power, contradicting the premise that it has a 128-bit key and is very difficult to break.
The Data Encryption Standard (DES) uses a 56-bit key, not a 128-bit key. Due to this relatively short key length, DES is no longer considered secure and can be broken with modern computational resources within a practical timeframe, making it unsuitable for protecting sensitive data.
