SHA-1
(Redirected from SHA1)
You are encouraged to solve this task according to the task description, using any language you may know.
SHA-1 or SHA1 is a one-way hash function; it computes a 160-bit message digest. SHA-1 often appears in security protocols; for example, many HTTPS websites use RSA with SHA-1 to secure their connections. BitTorrent uses SHA-1 to verify downloads. Git and Mercurial use SHA-1 digests to identify commits.
A US government standard, FIPS 180-1, defines SHA-1.
Find the SHA-1 message digest for a string of octets. You may either call a SHA-1 library, or implement SHA-1 in your language. Both approaches interest Rosetta Code.

Factor provides sha1 in the checksums.sha vocabulary. In Factor, checksum-bytes returns a sequence of bytes; hex-string converts this sequence to a hexadecimal string.

From J8 the ide/qt addon includes bindings to the Qt library function for a number of hash algorithms incluing SHA-1. Thus:
require '~addons/ide/qt/qt.ijs'
getsha1=: 'sha1'&gethash_jqtide_
getsha1 'Rosetta Code'
48c98f7e5a6e736d790ab740dfc3f51a61abe2b5
From J8.06, the sha family of hashes have builtin support.
sha1=:128!:6
sha1'Rosetta Code'
48c98f7e5a6e736d790ab740dfc3f51a61abe2b5

Remember that SHA-1 is an obsolete standard (and if you *really* want high speed you'd probably be using ASICs rather than a general purpose computing platform).
Java
The solution to this task would be a small modification to MD5 (replacing "MD5" with "SHA-1" as noted here).

Ruby
These programs print the SHA-1 of 'Rosetta Code', which is 48c98f7e5a6e736d790ab740dfc3f51a61abe2b5.
First: Use 'digest' from Ruby's standard library.
require 'digest'
puts Digest::SHA1.hexdigest('Rosetta Code')
Second: Use 'openssl' from Ruby's standard library.
require 'openssl'
puts OpenSSL::Digest::SHA1.hexdigest('Rosetta Code')
Third: Reimplement SHA-1 in Ruby.
require 'stringio'
# Calculates SHA-1 message digest of _string_. Returns binary digest.
# For hexadecimal digest, use +*sha1(string).unpack('H*')+.
