Cipher & Encryption Tools - AES, Blowfish, 3DES, RC4
3des Encrypt
Encrypt and decrypt with Triple DES (3DES/TDEA). Legacy encryption for banking, payment systems, and EMV cards. Free online 3DES tool.
Aes Encrypt
Encrypt and decrypt text with AES-256-GCM in your browser. Password-based encryption, Base64/Hex output. Private, secure, no server uploads.
Blowfish Encrypt
Encrypt and decrypt text with Blowfish cipher in your browser. Legacy 64-bit block cipher with variable key length. Free online Blowfish tool.
Caesar Cipher
Encode text with Caesar cipher using any shift value. Classic letter substitution from 1-25 positions. Educational cryptography tool, instant results.
Rc4 Cipher
Encrypt and decrypt with RC4 (ARC4) stream cipher. Legacy encryption for WEP, SSL analysis, and protocol research. Free online RC4 tool.
Rot13 Cipher
Encode and decode text with ROT13 cipher. Also supports ROT5 for numbers and ROT47 for ASCII. Simple letter substitution, instant results.
Vigenere Cipher
Encrypt and decrypt text using the Vigenère cipher. Use a keyword for stronger encryption than Caesar cipher. Includes frequency analysis.
Xtea Encrypt
Encrypt and decrypt with XTEA (eXtended TEA). Lightweight 64-bit block cipher for embedded systems and games. Free online XTEA tool.
Modern Encryption
Strong encryption protects sensitive data using mathematical algorithms. Our tools implement industry-standard ciphers for secure communication, file protection, and cryptographic testing.
Block Ciphers
AES (Advanced Encryption Standard) — The current standard for symmetric encryption. 128/192/256-bit keys with CBC mode.
Blowfish — Bruce Schneier's fast block cipher with 64-bit blocks. Popular in embedded systems and password hashing (bcrypt).
3DES (Triple DES) — Triple Data Encryption Standard for banking and payment systems. Still used in EMV cards and legacy financial systems.
XTEA — Tiny Encryption Algorithm for Arduino, embedded systems, and games. Minimal code footprint with reasonable security.
Stream Ciphers
RC4/ARC4 — Legacy stream cipher for analyzing old protocols, WEP research, and understanding cryptographic history. Deprecated for security but still found in legacy systems.
Classic Ciphers
ROT13 — Rotate letters 13 positions for casual obfuscation. Hide spoilers and puzzle answers.
Caesar Cipher — Historical cipher with configurable shift. Educational introduction to cryptography.
