:::::Indeed there is barely any crypto in this task, apart from the use of sha-256. It mainly consists in big integer arithmetic (and somehow the C code manages not to use big integer, I have to check it out) and byte string manipulations.--[[User:Grondilu|Grondilu]] 11:25, 29 November 2012 (UTC)
===C-based code (and possibly others) improperly validates===
Much of the code here does not check to make sure that the bitcoin addresses are 25-bytes. Hence, testing using the C-based code shows that it validates the invalid six-character bitcoin address "BZbvjr". However, trying to send to this address using the standard bitcoin client will naturally produce an error. I have edited the Perl implementation to make it work correctly, but someone who is a better coder than I should do it for the other languages too.

: The PHP code, C code, and probably many more of these snippets are incomplete implementations. I have added a warning at the top of the page to indicate this, as this page is linked to from [https://en.bitcoin.it/wiki/Address#Address_validation the bitcoin wiki].

== Base58Check encoding algorithm ==
This algorithm, "address validation", is not so popular... Is difficult to change its status of "snippets are incomplete".
It uses another algorithm inside it, that is simpler and popular, the [https://en.bitcoin.it/wiki/Base58Check_encoding Base58Check encoding algorithm]. So, creating it: [[Base58Check encoding]].
