@{b}DESCRIPTION@{ub}
|
|
sha is a simple program that hashes files. 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.
