User Experiences[edit]

7-zip can be used to open an ISO Image File[14].

In order to secure a transfer along untrusted lines, 7-Zip can encrypt containers with AES-256.

For securing fixity: 7-Zip records checksums on compression and verifies them on decompression.

7-Zip can handle containers larger than 2 GigaByte (unlike tools for the genuine ZIP format).

And there is a port of the command line version to Linux/Unix [15].
