Ciphers & Encryption
Symmetric encryption using AES-GCM, AES-CBC, ChaCha20-Poly1305, 3DES and classical ciphers. All tools run strictly inside your browser thread via the W3C Web Cryptography API with zero remote telemetry.
AES-256-GCM Encryptor & Decryptor
Authenticated encryption and decryption using AES-256-GCM (Galois/Counter Mode) via the native Web Cryptography API. Total data privacy.
AES-128-GCM Encryptor & Decryptor
Encrypt and decrypt data using 128-bit AES-GCM via browser WebCrypto. Fast, authenticated symmetric encryption.
AES-256-CBC Encryptor & Decryptor
Encrypt and decrypt using AES-256-CBC (Cipher Block Chaining) with PKCS#7 padding and random initialization vectors in your browser.
AES-128-CBC Encryptor & Decryptor
Encrypt and decrypt using 128-bit AES in CBC mode with PKCS#7 padding client-side.
AES-CTR Stream Encryptor & Decryptor
Encrypt and decrypt data using AES in Counter (CTR) mode. Converts block ciphers into stream ciphers with zero padding required.
ChaCha20-Poly1305 Encryptor
Encrypt data using ChaCha20-Poly1305 AEAD stream cipher. High-speed cipher used in WireGuard, TLS 1.3 and Android devices.
Triple DES (3DES) Encryptor
Encrypt and decrypt using Triple DES (EDE3 / 3DES) for legacy financial systems and banking smart card compliance.
DES Encryptor & Decryptor
Encrypt and decrypt data using the historic 56-bit Data Encryption Standard (DES). For cryptographic education and legacy research.
Blowfish Encryptor & Decryptor
Encrypt and decrypt text using Bruce Schneier's classic Blowfish symmetric block cipher with variable key lengths up to 448 bits.
RC4 Stream Cipher Encryptor
Encrypt and decrypt data using the classic Rivest Cipher 4 (RC4 / ARCFOUR) stream cipher for security research and WEP/SSL analysis.
XOR String Cipher Encryptor
Perform symmetric bitwise XOR encryption and decryption on strings with repeating multi-character keys.
ROT13 & Caesar Cipher Tool
Encrypt and decrypt text with ROT13, ROT47, and classical Caesar substitution ciphers with custom alphabet shift values.
About Ciphers & Encryption Architecture
Cryptographic operations in the Ciphers & Encryption suite are engineered to run client-side to prevent credential leakage. Whether processing private keys, password hashes, or security tokens, our platform guarantees that no sensitive bytes leave your workstation.
