🟩 Compute MD5, SHA1 or SHA256 hashes for a stream of bytes

The Hashing library abstracts OS API to compute MD5, SHA1 and SHA256 hashes.

Features

Hashing Algorithm	Description
SC::Hashing::TypeMD5	Compute MD5 hash for the incoming stream of bytes.
SC::Hashing::TypeSHA1	Compute SHA1 hash for the incoming stream of bytes.
SC::Hashing::TypeSHA256	Compute SHA256 hash for the incoming stream of bytes.

Status

🟩 Usable
The library is very simple it it has what is needed so far (mainly by Build).

Description

Compute MD5, SHA1 or SHA256 hash for stream of data.
Data can be added until needed with SC::Hashing::update call. SC::Hashing::finalize will generate an actual SC::Hashing::Result holding the computed hash.

Example:

            Hashing hash;
            SC_TEST_EXPECT(hash.setType(Hashing::TypeMD5));
 
            SC_TEST_EXPECT(hash.add("test"_a8.toBytesSpan()));
            Hashing::Result res;
            SC_TEST_EXPECT(hash.getHash(res));
 
            String test;
            SC_TEST_EXPECT(StringBuilder(test).appendHex(res.toBytesSpan(), StringBuilder::AppendHexCase::UpperCase));
            SC_TEST_EXPECT(test == "098F6BCD4621D373CADE4E832627B4F6"_a8);
            report.console.printLine(test.view());

Example with update (for hashing longer streams of data):

            Hashing hash;
            SC_TEST_EXPECT(hash.setType(Hashing::TypeMD5));
 
            SC_TEST_EXPECT(hash.add("test"_a8.toBytesSpan()));
            SC_TEST_EXPECT(hash.add("test"_a8.toBytesSpan()));
            Hashing::Result res;
            SC_TEST_EXPECT(hash.getHash(res));
 
            String test;
            SC_TEST_EXPECT(StringBuilder(test).appendHex(res.toBytesSpan(), StringBuilder::AppendHexCase::UpperCase));
            SC_TEST_EXPECT(test == "05A671C66AEFEA124CC08B76EA6D30BB"_a8);
