AES Encrypt / Decrypt

Encrypt text with authenticated AES-GCM using a 128, 192 or 256-bit key. A random salt and IV are embedded in the output so it can be decrypted later.

ModeAlgorithm

A forgotten password cannot be recovered. This is not a password manager.

실제 예제

Portable payload

입력: plain text + password
결과: opskit:aes-gcm:1:…

The output contains the random salt, IV and authenticated ciphertext, but not the password.

자주 틀리는 부분

Reusing a weak password

Encryption cannot compensate for a short or reused password. Use a long unique passphrase.

자주 묻는 질문

Which algorithm should I choose?

AES-256-GCM is the recommended default. All options use authenticated GCM and a key derived by PBKDF2-SHA-256 with 210,000 iterations.
