Documentation

This tool performs local Blowfish encryption/decryption with common modes and paddings, useful for legacy compatibility and education.

Key Features

  • Blowfish text encryption/decryption
  • CBC, ECB, CFB, and OFB modes
  • Multiple input/output formats
  • Custom key and IV inputs

Steps

  1. Choose encrypt or decrypt mode.
  2. Configure mode, padding, and key settings.
  3. Enter plaintext or ciphertext.
  4. Process and copy the output.

Notes

  • Blowfish uses 64-bit blocks and is less ideal for new large-scale systems.
  • Prefer modern 128-bit block ciphers such as AES for new projects.
  • Avoid short keys and ECB mode when possible.
