Abstract
DNAcrypt-AI is a human genome-inspired cryptographic framework that leverages k-mer-based alphanumeric and symbol encoding, genome vocabulary, sequence reconstruction, and sequence-informed machine learning to generate and encrypt digital credentials as genome coordinates. This protocol describes the procedure for generating a fixed-length password (16 characters) and encrypting it using DNAcrypt-AI. The pipeline is implemented on Google Colab and integrates a high-throughput DNA sequence reconstitution pipeline (FAS2rDNA) with a sequence intelligence model (Covary) to randomly generate a plaintext password into an encrypted, non-human-readable genome metadata representation. The protocol generated the expected password text of 16 characters long and provided an encryption data that can be used for decryption and password recovery.
Troubleshooting
Protocol procedure
Launch DNAcrypt-AI from https://dnacryptai.chordexbio.com/
Alternatively, you can run DNAcrypt-AI using the recommended methods described in https://github.com/mahvin92/DNAcrypt-AI
Create a configuration by modifying the user interface, as shown in Figure 1 below.
Figure 1. The interface of user configuration on DNAcrypt-AI, where users can specify the behavior of the cipher.
Type the number 16 in the char_count text box.
Note that users can generate passwords with length from 6 to 90 characters.
Select the Password checkbox, ensuring to uncheck the other options under the Use cases section
Run DNAcrypt-AI by initiating a runtime, ensuring a GPU (T4 as default) support, if available.
Initiate a runtime:
Click 'Runtime' -> Select 'Run all'
Note that DNAcrypt-AI will still work in a non-GPU hosted runtime.
Wait for DNAcrypt-AI to finish running. The status and any error will be displayed below the code cell.
Allow the browser to download the DNAcrypt_metadata.json file. This is your encrypted data and is recommended to be renamed.
Note that if no download is produced, you can fetch the file from the /content/ directory through the File browser.
Save and store your encryption, digitally or physically by printing a copy.
Note that the encryption data is light and about 200kb in size only. When storing the data as a physical copy, ensure to print legibly to allow encoding to a digital copy later on for recovery.
Application note
This protocol is designed for generating secure, non-human-readable passwords encoded as human genome coordinates. It is suitable for cryptographic demonstrations, secure credential generation, and experimental DNA-based security research.
