| - | * **Optimized Fast ** – automatically selects best compression method to use based on file extension. Priority in Optimized Fast mode is speed of compression and extraction. At minimum there should be 50 MB/s speed for extraction of files, depending on your HDD. Up to 400 MB/s is possible depending on settings selected, with compression always better than ZIP. | + | * **Optimized Fast ** – automatically selects best compression method to use based on file extension.

| ===== Compression ===== | ===== Compression ===== | ||
| - | * **Ultra** – Best compression possible at slowest speed. Up to 750 MB RAM required only for Optimized/LZMA method. | + | * **Extreme** – Best compression possible at slower speed. Extra extensions are added to stronger codecs to ensure maximum compression. |
| - | * **Maximum** – Good balance between maximum compression and less memory usage – 400 MB RAM required only for Optimized/LZMA method. | + | * **Ultra** – Very strong compression with decent speed. Still very usable. |
| + | * **Maximum** – Good balance between maximum compression, good extraction speed and less memory usage. | ||

| + | |||
| + | * **Disabled** - disables encryption for ZIP archives. | ||
| + | * **Secure AES 256-bits** - creates PA archives with AES 256-bit encryption. For added security, we use the BWTS algorithm to scramble the data before AES, so attackers can not use LZ compression redundancy and other plaintext attacks to quickly check if given password is valid. This makes .pa format considerably more secure than ZIP AES. For the AES encryption module, we use FIPS 140-2 validated modules from Windows so you can rest assured that AES implementation has been tested and validated (FIPS 140-2 encryption module is always used). | ||

| - | While PK 2.04g encryption can be read by all Zip utilities, this method uses weak encryption that can be broken. You should use .PAE encryption, 7-Zip or ZIP AES encryption if you require real security. We do not recommend using both 7-Zip/ZIP Encryption and .PAE encryption at the same time. You can find out more about secure encryption here.// | + | While PK 2.04g encryption can be read by all Zip utilities, this method uses weak encryption that can be easily broken.
