OpsKit

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.

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

什么时候用得上

  • Protecting a small note before storing or sending it.
  • Testing AES-GCM integrations.
  • Creating temporary encrypted text without uploading plaintext.

实际示例

Portable payload

输入
plain text + password
结果
opskit:aes-gcm:1:…

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

容易出错的地方

Reusing a weak password

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

常见问题

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.
