Cryptography
Tools for hashing, encryption, and generating secure identifiers
Understanding Cryptography
Cryptography is essential for securing data and communications in modern applications. Our cryptography tools provide developers with utilities for implementing common security features and working with cryptographic functions.
Hash Functions
One-way cryptographic functions that generate a fixed-size string from input data of any size. Used for data integrity verification, password storage, and checksums.
UUID Generation
Universally Unique Identifiers (UUIDs) are 128-bit identifiers guaranteed to be unique. Used for database keys, session IDs, and any scenario requiring unique identifiers.
Encryption
The process of encoding information to prevent unauthorized access. Our tools support symmetric encryption algorithms using the same key for both encryption and decryption.
Client-Side Security
All our cryptography tools operate entirely in your browser, ensuring sensitive data never leaves your device for enhanced privacy and security.
Security Considerations
Algorithm Selection
For security-critical applications, use SHA-256 or stronger hash algorithms. MD5 and SHA-1 are no longer considered secure for cryptographic purposes.
Production Use
For production applications, use established cryptographic libraries and follow security best practices specific to your platform.
Key Management
Secure key management is critical for encryption. Never hardcode keys in your application and use proper key rotation practices.
Expert Consultation
For critical security applications, consult with security experts and use well-audited, platform-specific cryptographic implementations.
