Blowfish is a symmetric-key block cipher designed in 1993 by Bruce Schneier. It is known for its speed and security and has been widely used in various cryptographic applications. The Blowfish algorithm is also used for password hashing through the bcrypt algorithm, which is based on Blowfish and adds a salt and cost factor to protect against brute-force attacks.
Blowfish is widely used in various security applications:
| Application | Usage |
|---|---|
| Password Storage | Secure storage of passwords in databases |
| File Encryption | Encryption of files and sensitive data |
| Secure Communications | Protection of data in transit over networks |
| VPNs | Some VPN implementations use Blowfish for encryption |
| Algorithm | Output Size | Security Status | Common Uses |
|---|---|---|---|
| Blowfish (bcrypt) | 60 characters | Secure | Password hashing |
| MD5 | 128 bits | Broken | Checksums, legacy systems |
| SHA-1 | 160 bits | Vulnerable | Git, legacy certificates |
| SHA-256 | 256 bits | Secure | Cryptography, blockchain, certificates |
💡 For password hashing, Blowfish (through bcrypt) is considered one of the most secure options due to its adaptive cost factor which makes it resistant to brute-force attacks.
