API Key Generator

Text to Hash

MD5Not for security

128 bits (32 hex characters)

SHA-1Deprecated

160 bits (40 hex characters)

SHA-256Recommended

256 bits (64 hex characters)

SHA-512

512 bits (128 hex characters)

Security Note: Never use MD5 or SHA-1 for passwords or security-critical applications. For password hashing, use specialized algorithms like bcrypt, scrypt, or Argon2. These hash functions are suitable for checksums and data integrity verification.
