SHA-1: Difference between revisions

This is much faster than a brute force attack of 2⁸⁰ operations. USgovernment [http://csrc.nist.gov/groups/ST/hash/statement.html deprecated SHA-1].

For production-grade cryptography, users may consider a stronger alternative, such as SHA-256 (from the SHA-2 family) or the upcoming SHA-3.}}

=={{header|J}}==

From J8 the <tt>ide/qt</tt> addon includes bindings to the Qt library function for a number of hash algorithms incluing SHA-1. Thus:

getsha1=: 'sha1'&gethash_jqtide_

getsha1 'Rosetta Code'

 

From J8.06, the sha family of hashes have builtin support.

 

sha1'Rosetta Code'

 

A implementation of SHA-1 in J follows:

 

 

f=:4 :0

)

 

 

Example use:

 

bits2hex=: '0123456789abcdef' {~ _4 #.\ ,

 

bits2hex sha1 text2bits 'Rosetta Code'

 

Remember that SHA-1 is an obsolete standard (and if you *really* want high speed you'd probably be using [[wp:Application-specific_integrated_circuit|ASICs]] rather than a general purpose computing platform).

The solution to this task would be a small modification to [[MD5#Java|MD5]] (replacing "MD5" with "SHA-1" as noted [http://docs.oracle.com/javase/7/docs/technotes/guides/security/StandardNames.html#MessageDigest here]).
