Private by design
Turn a file into an encrypted DNA sequence.
The file is encrypted in your browser before it becomes A, C, G and T. Possessing the sequence is not enough—the correct password is required to authenticate and restore the original file.
AES-256-GCM
PBKDF2-SHA-256
No server upload
Saved encrypted projects
Encrypt and encode
Create a password-locked DNA sequence.
Everything happens locally in this browser. The password is never saved inside a project and is never transmitted by this page.
1. Choose the file
DNA text is large: every encrypted byte becomes four DNA letters. A 1 MB image produces slightly more than four million bases.
2. Set the secret password
Use 12+ characters
Encrypted DNA sequence ready
Password requiredThe sequence contains authenticated ciphertext. A wrong password or altered sequence will fail to decrypt.

Send the password separately—for example, share the sequence by email and the password by a phone call or trusted encrypted messenger.
Authenticate and restore
Unlock a DNA sequence with its password.
Paste the sequence or load a .dna/.txt file. The original file is restored only when the password and authentication data are correct.
1. Add the DNA sequence
2. Enter the password
Decryption is performed locally. This page does not upload the sequence or password.
File restored
AuthenticatedThe password is correct and the sequence passed authentication.
