Text encoding, cryptographic hashing, symmetric & asymmetric encryption.
About Cryptography Toolkit
Overview
This toolkit integrates 20+ industry-standard cryptographic algorithms, covering four major categories: text encoding, cryptographic hashing, symmetric encryption, and asymmetric encryption.
100% Client-Side Processing—
Zero Network Transmission:
All cryptographic operations are performed locally on your device. All sensitive data (plaintext, ciphertext, keys, etc.) never leaves your device, ensuring complete privacy and security.
Select a specific algorithm to view detailed technical documentation, including algorithm history, security analysis, recommended parameters, and professional guidance.

Base64
Base64 is an RFC 4648-compliant encoding scheme that represents binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). Every 3 bytes of input are encoded as 4 characters.
Key Features: Increases data size by ~33% but enables safe transmission of binary data over text-based protocols.
Why Use This: Base64 is the de facto standard for encoding binary data in text contexts—widely used in email attachments (MIME), data URIs, JWT tokens, and API payloads. While it provides no encryption, it's essential for data interchange in text-only environments.
