std.digest.ripemd
Computes RIPEMD-160 hashes of arbitrary data. RIPEMD-160 hashes are 20 byte quantities
that are like a checksum or CRC, but are more robust.

Examples:
//Template API import std.digest.md; ubyte[20] hash = ripemd160Of("abc"); writeln(toHexString(hash)); // "8EB208F7E05D987A9B044A8E98C6B087F15A0BFC" //Feeding data ubyte[1024] data; RIPEMD160 md; md.start(); md.put(data[]); md.start(); //Start again md.put(data[]); hash = md.finish();
Examples:
//OOP API import std.digest.md; auto md = new RIPEMD160Digest(); ubyte[] hash = md.digest("abc"); writeln(toHexString(hash)); // "8EB208F7E05D987A9B044A8E98C6B087F15A0BFC" //Feeding data ubyte[1024] data; md.put(data[]); md.reset(); //Start again md.put(data[]); hash = md.finish();
- struct
RIPEMD160
; - Template API RIPEMD160 implementation. See std.digest for differences between template and OOP API.Examples:
//Simple example, hashing a string using ripemd160Of helper function ubyte[20] hash = ripemd160Of("abc"); //Let's get a hash string writeln(toHexString(hash)); // "8EB208F7E05D987A9B044A8E98C6B087F15A0BFC"
Examples://Using the basic API RIPEMD160 hash; hash.start(); ubyte[1024] data; //Initialize data here... hash.put(data); ubyte[20] result = hash.finish();
Examples://Let's use the template features: void doSomething(T)(ref T hash) if (isDigest!T) { hash.put(cast(ubyte) 0); } RIPEMD160 md; md.start(); doSomething(md); writeln(toHexString(md.finish())); // "C81B94933420221A7AC004A90242D8B1D3E5070D"
Examples://Simple example RIPEMD160 hash; hash.start(); hash.put(cast(ubyte) 0); ubyte[20] result = hash.finish(); writeln(toHexString(result)); // "C81B94933420221A7AC004A90242D8B1D3E5070D"
- pure nothrow @nogc @trusted void
put
(scope const(ubyte)[]data
...); - Use this to feed the digest with data. Also implements the std.range.primitives.isOutputRange interface for ubyte and const(ubyte)[].
Example
RIPEMD160 dig; dig.put(cast(ubyte) 0); //single ubyte dig.put(cast(ubyte) 0, cast(ubyte) 0); //variadic ubyte[10] buf; dig.put(buf); //buffer
- pure nothrow @nogc @safe void
start
(); - Used to (re)initialize the RIPEMD160 digest.
Note For this RIPEMD160 Digest implementation calling start after default construction is not necessary. Calling start is only necessary to reset the Digest.
Generic code which deals with different Digest types should always call start though.Example
RIPEMD160 digest; //digest.start(); //Not necessary digest.put(0);
- pure nothrow @nogc @trusted ubyte[20]
finish
(); - Returns the finished RIPEMD160 hash. This also calls start to reset the internal state.
Example
//Simple example RIPEMD160 hash; hash.start(); hash.put(cast(ubyte) 0); ubyte[20] result = hash.finish(); assert(toHexString(result) == "C81B94933420221A7AC004A90242D8B1D3E5070D");
- auto
ripemd160Of
(T...)(Tdata
); - This is a convenience alias for std.digest.digest using the RIPEMD160 implementation.Examples:
ubyte[20] hash = ripemd160Of("abc"); writeln(hash); // digest!RIPEMD160("abc")
- alias
RIPEMD160Digest
= std.digest.WrapperDigest!(RIPEMD160).WrapperDigest; - OOP API RIPEMD160 implementation. See std.digest for differences between template and OOP API.This is an alias for std.digest.WrapperDigest!RIPEMD160, see there for more information.Examples:
//Simple example, hashing a string using Digest.digest helper function auto md = new RIPEMD160Digest(); ubyte[] hash = md.digest("abc"); //Let's get a hash string writeln(toHexString(hash)); // "8EB208F7E05D987A9B044A8E98C6B087F15A0BFC"
Examples://Let's use the OOP features: void test(Digest dig) { dig.put(cast(ubyte) 0); } auto md = new RIPEMD160Digest(); test(md); //Let's use a custom buffer: ubyte[20] buf; ubyte[] result = md.finish(buf[]); writeln(toHexString(result)); // "C81B94933420221A7AC004A90242D8B1D3E5070D"
