Encode, decode, and generate hashes securely. Free encryption tools, no signup required. Base64, AES encryption & hash generators. All tools run locally in your browser—no signup or registration required.
Cryptography tools are vital for developers and security professionals. Use Base64 encoding for API integration and data transmission. Generate hash values (MD5, SHA-256) to verify file integrity or create checksums. Encrypt sensitive text or files with AES encryption before transmission. Perfect for API testing, password storage verification, data integrity checks, and secure communication workflows.
Choose your cryptography tool based on your need. For Base64 encoding, simply paste text or upload files. For hash generation, select your algorithm (MD5, SHA-1, SHA-256, etc.) and input your text or file. For encryption, choose your method (AES, DES, TripleDES) and provide a secure key. All cryptographic operations execute locally in your browser—your sensitive data never touches our servers.
