Cara Cek SHA256sum

Setelah mendownload file .iso (atau mungkin file apapun) pastikan untuk mengecek bahwa file yang kita download sudah sempurna/tidak corrupt.
SHA256 checksum lebih baik daripada MD5 checksum.

Penggunaan SHA256

shasum -a 256 <file.ISO>

contoh :

shasum -a 256 ubuntu-11.04-desktop-i386.iso

Hasil yang muncul di terminal

ccb7e6f1d1575f92f76e61413bd5b2235dd86c4e9a47b5d74bfe8352e95b9699 ubuntu-11.04-desktop-i386.iso

In the 1940s the United States military asked Johnson & Johnson to devise “a waterproof, strong cloth based tape that could keep moisture out of ammunition cases.” The result was a superhero adhesive tape made from a rubber-based adhesive applied to a durable duck cloth backing. Originally called duck tape, due to its cotton duck substrate, at some point during the last half of the 20th century it became better known as duct tape, owing to its employment in ductwork.

But over the years something else evolved with the product along with its name. It became the absolute darling of the do-it-yourself set — the indispensable item in the tool box, craft room, car trunk, back pack, sports bag and junk drawer, not to mention submarines andNASA spaceships. It's the sine qua non for emergency hacks and for making do with what you have. And its durability makes it an integral component in extending the life of broken things, giving them a new lease on life and keeping them out of the rubbish heap. And although to some, duct tape crafts and repairs may scream, "low-rent and tacky," we're seeing a shift in the zeitgeist that suggests a new era of duct-tape chic is in the air. So find some inspiration here and get taping.
