PNA (Portable Network Archive) is a highly scalable archive format that can be compressed, encrypted, and split. Also, its data structure is inspired by the PNG data structure.
Portable Network Archive (PNA): A Flexible, Secure, and Cross-Platform Archive Format
- Portability: Works seamlessly across multiple platforms, combining the strengths of TAR and ZIP formats.
- Compression Flexibility: Advanced per-file and archive-wide compression options reduce the need for full archive decompression.
- Encryption & Security: Supports 256-bit AES and Camellia for robust protection of sensitive data.
- Splittable Structure: Based on PNG’s data unit structure, enabling the easy division of large archives into smaller parts.
- Streamability: Supports serial read and write operations, making it suitable streaming processing, similar to a TAR format.
- Extensibility: Designed to accommodate future extensions and private add-ons, ensuring compatibility with the basic PNA format while allowing for flexible customization.
- Error Resilience: File integrity checks and error detection ensure data is secure during transmission.
Additionally, the PNA specification includes a rationale appendix to help developers understand key design choices, making implementation more straightforward.
-
File Compression and Decompression
- Supports zlib, zstd, and xz.
-
File Encryption and Decryption
- Supports 256-bit AES and 256-bit Camellia.
-
Solid Mode
- Compresses and encrypts the entire archive as a single block.
-
File Attribute Preservation (Maintains and restores)
- File permissions.
- File timestamps.
- Extended attributes.
- Access Control Lists (ACLs) (experimental).
PNA (Portable Network Archive) CLI is cross-platform and compatible with the following operating systems:
- Windows
- Linux
- macOS
- FreeBSD
This compatibility ensures that users can utilize PNA across different environments without any platform-specific limitations.
Further supported operating systems will be added in the future.
