Encrypt & Decrypt Text with Argon2id

Protect sensitive messages in the browser using Argon2id-derived keys and AES-GCM, then share Base64 payloads securely.

Encrypt Text

Password

Text to Encrypt 0 / 5000

Time Cost (Iterations) 3 Higher values increase key-derivation time but improve resistance to brute-force attacks.

Memory Cost (MB) 128 MB Allocated RAM for Argon2id (higher consumes more memory but hardens GPU attacks).

Parallelism 4 Number of CPU threads used during key derivation.

Password

Encrypted Text to Decrypt 0 / 5000

Time Cost (Iterations) 3 Match the iterations used during encryption.

Memory Cost (MB) 128 MB Ensure this matches the memory setting used for encryption.

Parallelism 4 Use the same thread count you selected when encrypting.
