AES-GCM Encrypt
Encrypt text with authenticated AES-GCM.
Note: The key is derived from the password with SHA-256 and a fresh random IV is used for every encryption. The output format is iv:ciphertext as lowercase hex. For AES-GCM the ciphertext is authenticated (tamper and wrong-password detection); CBC and CTR are not — use GCM for secure data.
What Is a AES-GCM Encrypt?
The AES-GCM Encrypt tool encrypts text with AES in Galois/Counter Mode, the recommended authenticated mode of operation. GCM produces both encrypted data and an authentication tag, so the AES Decrypt tool can detect any tampering or an incorrect password. This free online tool is useful for AES-GCM encryption tool, AES GCM online, authenticated encryption. Common use cases include API payload protection, secure application development, encryption testing, and learning AEAD. It is designed for quick browser-based hashing, encoding, decoding, encryption testing, checksum comparison, identifier generation, and cryptography education. For production security, follow the algorithm's current standards, key-management requirements, and application-specific security guidance.
