"WebDec 14, 2024 · It is common and usual for a symmetric key, such as used by Blowfish, AES, etc, to be much smaller than the data and this does not reduce the security. The security is determined by a secure encryption method such as AES and the key size. AES has key sizes of 128, 192 or 256-bits and essentially has no size limit. – zaph Dec 15, 2024 at 16:11 " - Blowfish symmetric cryptosystems
