Is 7-Zip really a good encryption tool? I wonder what kind of encryption is used in 7-zip. I see most people using 7-Zip. Just curious about what extent it is safe.

It uses AES-256 with PBKDF2 using SHA1 with only 1,000 iterations [number disputed in 2nd and 3rd comment] as the KDF. The AES-256 is strong, but the password protection is weak so make sure you use good passwords.
