448 bit encryption

Blowfish Encryption. The Blowfish algorithm is a symmetric block cipher that can be used as a drop-in replacement for DES or IDEA. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use.

Blowfish has a 64-bit block size whereas AES has a 128-bit block size, so you are sort of comparing apples and oranges (there are some things you can do in AES which would be unwise in Blowfish, in particular Blowfish in CTR mode can be distinguished from a random stream after only a few dozen gigabytes of output - see fgrieu's answer here, replacing 128 by 64 in the calculations). The 2048-bit is about the RSA key pair: RSA keys are mathematical objects which include a big integer, and a "2048-bit key" is a key such that the big integer is larger than 2 2047 but smaller than 2 2048.. The 256-bit is about SSL. Even though 448-bit encoding is extremely big digit and comes with more security and safety but to be fair, AES 256-bit has faced more testing as compared to 448-bit encoding. It is advised to use industry proven standard of AES 256-bit encryption so, it would be stupid to move to another encryption standard just because it sounds better. Blowfish is a variable-length key, 64-bit block cipher. The algorithm consists of two parts: a key-expansion part and a data- encryption part. Key expansion converts a key of at most 448 bits into several subkey arrays totaling 4168 bytes. Data encryption occurs via a 16-round Feistel network. Cypherix® announces the release of Cryptainer LE (12.0 series), the free 448 bit encryption software. Cryptainer LE encrypts any type of data on any Windows PC on any kind of media. Specially tailored to answer security and privacy needs of the average PC, Cryptainer LE combines ease of use and simple drag-and-drop operations. Blowfish is a 16 round feistel chiper that has key lenght from 32 to 448-bit and use large key dependent s boxes. Blowfish is similar to Cast 128 structuraly. In blowfish, every line represents 32 bits. Two subkey arrays are kept the 18 entry P-array and four 256-entry S boxes, which takes 8 bit input while producing 32 bit output. Blowfish is a brute-force resistant encryption algorithm, that requires over 500 iterations (i think like 508) of the algorithm to test a single key. The full encryption key length is used, 448 bits.

Ok. So I recently signed up for Crashplan which uses 448-bit Blowfish to encrypt the data you send them, and the more I do research on Blowfish the more it sounds like the 64-bit block size is totally insufficient for the size of the volumes they will be backing up.

Blowfish was developed in the early 1990s as a potential replacement for DES, though AES ultimately became the agreed standard form of encryption. It is a cipher supporting variable key lengths from 1 to 448 bits.

The Blowfish algorithm is a symmetric block cipher that can be used as a drop-in replacement for DES or IDEA. It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use. The encryption of the data 64-bit input is denoted with an x, while the P-array is denoted with a Pi (where i is the iteration). 6 The Blowfish Algorithm Key Expansion (cont) Blowfish has a 64-bit block size and a key length of anywhere from 32 bits to 448 bits (32-448 bits in steps of 8 bits default 128 bits). Bcrypt is a cross platform file encryption utility. Encrypted files are portable across all supported operating systems and processors. Passphrases must be between 8 and 56 characters and are hashed internally to a 448 bit key. However, all characters supplied are significant. The stronger your passphrase, the more secure your data.
