Set minimum size of symmetric encryption
Summary​
The symmetric encryption mechanism must use a minimum key size of 128 bits.
Description​
As the key size increases, the number of possible key combinations grows significantly. Each additional bit in the key size doubles the number of possible keys. A 128-bit key provides a larger key space compared to shorter key sizes, making it more resistant to brute force attacks. Widely used symmetric encryption algorithms, such as Advanced Encryption Standard (AES), use a 128-bit key size as the default or minimum recommended key length.
