- struct SHA1;
- Template API SHA1 implementation.
See std.digest.digest for differences between template and OOP API.
Examples:
//Simple example, hashing a string using sha1Of helper function ubyte[20] hash = sha1Of("abc"); //Let's get a hash string assert(toHexString(hash) == "A9993E364706816ABA3E25717850C26C9CD0D89D");
Examples://Using the basic API SHA1 hash; hash.start(); ubyte[1024] data; //Initialize data here... hash.put(data); ubyte[20] result = hash.finish();
Examples://Let's use the template features: //Note: When passing a SHA1 to a function, it must be passed by referece! void doSomething(T)(ref T hash) if(isDigest!T) { hash.put(cast(ubyte)0); } SHA1 sha; sha.start(); doSomething(sha); assert(toHexString(sha.finish()) == "5BA93C9DB0CFF93F52B521D7420E43F6EDA2784F");
- auto sha1Of(T...)(T data);
- This is a convenience alias for std.digest.digest.digest using the
SHA1 implementation.
Examples:
ubyte[20] hash = sha1Of("abc"); assert(hash == digest!SHA1("abc"));
- alias SHA1Digest = std.digest.digest.WrapperDigest!(SHA1).WrapperDigest;
- OOP API SHA1 implementation.
See std.digest.digest for differences between template and OOP API.
This is an alias for std.digest.digest.WrapperDigest!SHA1, see
std.digest.digest.WrapperDigest for more information.
Examples:
//Simple example, hashing a string using Digest.digest helper function auto sha = new SHA1Digest(); ubyte[] hash = sha.digest("abc"); //Let's get a hash string assert(toHexString(hash) == "A9993E364706816ABA3E25717850C26C9CD0D89D");
Examples://Let's use the OOP features: void test(Digest dig) { dig.put(cast(ubyte)0); } auto sha = new SHA1Digest(); test(sha); //Let's use a custom buffer: ubyte[20] buf; ubyte[] result = sha.finish(buf[]); assert(toHexString(result) == "5BA93C9DB0CFF93F52B521D7420E43F6EDA2784F");
