If the file contains lines with salt, you can skip them to save time.
If the "Skip salt" checkbox is checked, then all lines with the found salt will be written to a separate file with the "_salt" postfix.
What is considered salt?
The program considers a string with salt if it matches one of the formats:
ITEM: HASH: SALT
HASH: SALT: ITEM
Can salt decrypt?
Salted hashes can only be decrypted using graphics card resources. However, the program cannot unambiguously understand salted hashes or not. If the program detects salty hashes, you should try to disable the salt skip function and start the file with the "_salt" postfix for processing.
