Another thread addresses the question of what can count as "military-grade encryption." In this case, I see that CyberLink Power2Go software boasts "advanced military-grade 256-bit encryption." TechRadar clarifies that … Continue reading Military-grade encryption on Blu-ray discs?
As per this question from Ask Ubuntu, I ran a test on two .7z files with:
7z l -slt somefile.7z
Two different 7zip archives gave slightly different outputs:
1)

The 7z format supports encryption with the AES algorithm with a 256-bi… Continue reading Does 7-Zip really run multiple rounds of SHA-256 when key stretching?
Is there an application to create an archive (e.g. 7z, zip, rar, etc) that can be accessed with multiple valid passwords?
For example the password protected archive "example.7z" can be extracted using either "Passw0rd",… Continue reading Application to archive a file with multiple passwords [duplicate]
