- Zip Encryption
Zip archives can use two encryption algorithms, AES and old encryption, and Snowflower Arc supports decompression of all of these algorithms. However, the Snowflower Arc supports decompression of all of these algorithms. however, the older encryption in Zip is known to be very weak, so for security reasons we only support strong encryption with AES.
- 7z Encryption
The 7z archive you can use the algorithm of AES. In Snowflower Arc extension only to support.
