It uses the National Institute of Standards and Technology's Secure Hash Algorithm. It can use SHA-1, SHA-256, SHA-384, or SHA-512, which generate respectively, hashes of 160, 256, 384, or 512 bits. @{b}sha@{ub} can be used in scripts to do, for example, file integrity checking. @{b}OPTIONS@{ub} @{b}SHA1@{ub} Use SHA1, which produces a 160-bit hash (40 hex digits). @{b}SHA256@{ub} Use SHA256, which produces a 256-bit hash (64 hex digits). @{b}SHA384@{ub} Use SHA384, which produces a 384-bit hash (96 hex digits). @{b}SHA512@{ub} Use SHA512, which produces a 512-bit hash (128 hex digits). @{u}file@{uu} ... One or more files to hash. @{b}AUTHOR@{ub} The original sha utility was developed by Allan Saddi. The Amiga version is being developed and maintained by Carsten Larsen. @{bg filltext}@{b} June 11, 2015 SHA@{ub}@{bg background} @endnode
