Calculate SHA-1 digests in Elm.
This package can take a message as a String or List Int ("bytes") calculate
SHA-1 digests, and represent them in hexadecimal, base64 or a List Int (as
"bytes").
Please note that there was an issue regarding input data of 311 bytes in versions 1.0.0 and 1.0.1 of this library. If you are using either of these versions, it is highly recommended that you upgrade as soon as possible.
import SHA1
digest1 : SHA1.Digest
digest1 = SHA1.fromString "string"
digest2 : SHA1.Digest
digest2 = SHA1.fromBytes [0x00, 0xFF, 0xCE, 0x35, 0x74]
SHA1.toHex digest1

Tested against hashes in tests/Tests.elm, indirectly in romariolopezc/elm-hmac-sha1’s tests, and personal use of and the tests for TSFoster/elm-uuid.
Please note that SHA-1 is not “considered secure against well-funded opponents”, but it does have its uses, including, but not limited to, version 5 UUIDs.
