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.

URL Encoding
URL Encoding (percent-encoding) is defined by RFC 3986 for safely transmitting special characters in URLs. It converts non-ASCII and reserved characters to %XX format, where XX is the character's hexadecimal value.
Key Features: Only encodes special characters while preserving ordinary characters, maintaining partial readability.
Use Cases: Essential for web development—used in URL parameters, form submissions, and HTTP requests. Note: URL encoding is not encryption and provides no security protection; it's purely for data format conversion.
