AES-CTR Encrypt
Encrypt text with AES-CTR.
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-CTR Encrypt?
The AES-CTR Encrypt tool encrypts text with AES in Counter mode. CTR turns AES into a stream cipher by encrypting a counter block and XORing the result with the plaintext, making it parallelizable and fast. It is used in TLS, IPsec, and many modern systems.
How to Use This AES-CTR Encrypt
- 1Enter PasswordType the password used to derive the key.
- 2Enter TextType your plaintext.
- 3EncryptClick 'Encrypt CTR' to produce the iv:ciphertext output and copy it.
