Blowfish Encryption

Blowfish Info

Fast & Efficient

Blowfish is significantly faster than DES and can be used as a drop-in replacement

Variable Key Length

Supports keys from 32 to 448 bits (4 to 56 bytes)

64-bit Blocks

Processes data in 64-bit blocks for efficient encryption

Example Inputs

Quick Tips

  • Use CBC mode for better security
  • Generate random keys (256-bit recommended)
  • Always use IV for CBC, CFB, OFB modes
  • Keep your encryption key secret
  • Use same settings for encrypt/decrypt
