All notable changes to this package will be documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

• Hybrid encryption support: Integrated RSA and AES encryption mechanisms for secure data encryption and decryption.
• Digital signature generation: Added support for generating digital signatures for payloads using RSA private keys.
• Public key and private key loading: Functions to load RSA keys from PEM files.
• Encrypted data validation: Added method to verify the integrity of encrypted data (validating the IV, encrypted key, and data format).
• Base64 encoding/decoding: Functions to handle Base64 encoding of encrypted data, keys, and signatures.

Changed

• Code structure refactor: Improved code readability and modularity for better maintainability.
• Error handling: Enhanced error messages and exception handling for better debugging.

Fixed

[1.0.0] - 2024-11-18

Added

• Initial release of Gunjancryption package with the following features:
  • Hybrid RSA-AES Encryption: Allows encryption and decryption of data using a combination of RSA (for key exchange) and AES (for data encryption).
  • Digital Signature Generation: Supports generating and verifying digital signatures using RSA.
  • RSA Key Loading: Can load RSA public and private keys from PEM files for encryption and decryption operations.
  • Encrypted Data Verification: Validates the structure and integrity of encrypted data.
  • Utility Methods: Includes helper methods for Base64 encoding and decoding, used for secure data transfer and storage.

Fixed

• Resolved issues related to the improper handling of Base64 encoding/decoding in encrypted data and keys.
