AzCryptor

AzCryptor - Secure File Encryption Solution

command-line (CLI) tool for encrypting and decrypting files using the hybrid AES + RSA algorithm.

Key Features

• Hybrid Encryption: AES-256 for data + RSA-2048 for keys
• Automatic Key Generation: Automatic RSA key pair generation during encryption
• Secure Key Management: Secure storage of private keys for decryption
• Large File Support: Suitable for backups, archives, and databases
• Cross-Platform: Runs on Windows, Linux, and Mac
• Simple Interface: Fast and easy command-line interface

Installation

npm install azcryptor --global

Usage :

To encrypt a file :

azcryptor encrypt -i input-file-name -o encrypted-output-file-name -m meta-files-output-folder

To decrypt :

Please copy the meta files along with the encrypted file and then proceed:
azcryptor decrypt -i encrypted-file-name -o decrypted-output-file-name

D:\input └── myFile.rar ← Original file

D:\output └── myFile.rar.enc ← Encrypted file

D:\meta ├── myFile.rar.enc.key ← AES encryption key ├── myFile.rar.enc.iv ← IV value └── myFile.rar.enc.private.pem ← RSA private key

D:\decrypted └── myFile_restored.rar ← Restored file

Important Security Notes

• The encryption keys are generated each time, and you will need these exact same files for decryption.
• Keep the encryption keys in a secure location.
• Without encryption keys , decryption is impossible.
• For enhanced security, encrypt the .key and .iv files
• Do not send the encryption keys along with the encrypted file.
• Note: AzCryptor only encrypts file contents, not file names or paths
