Definition - What does Blowfish mean?
Blowfish is a license-free cipher-block algorithm that propels a 32-bit, variable-length key to 448 bits. The original design was intended to replace the older and less-advanced data encryption standard (DES) by way of public domain access. Its basic functions utilize S-keys, which are key-dependent.
Techopedia explains Blowfish
Bruce Schneier developed the blowfish algorithm in 1993. While seemingly taking too much time to gain technological acceptance, the blowfish algorithm has been given significant numbers of positive reviews.
