Hash

The Hash: module provides hashing and Base64 encoding. All methods are ByRef. Implementations are self-contained — no external library required.

Call	Effect
`Hash:MD5(str, outVar)`	MD5 digest → 32-char lowercase hex → `outVar`
`Hash:SHA256(str, outVar)`	SHA-256 digest → 64-char lowercase hex → `outVar`
`Hash:Base64Encode(str, outVar)`	Base64-encode string → `outVar`
`Hash:Base64Decode(str, outVar)`	Base64-decode string → `outVar`

Hash:MD5 and Hash:SHA256 are not cryptographically secure for new systems — use them for checksums and compatibility only.

Var:String h;
Hash:MD5("hello", h);
Konsol:Print(h);        // 5d41402abc4b2a76b9719d911017c592

Hash:SHA256("hello", h);
Konsol:Print(h);        // 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

Var:String enc;
Hash:Base64Encode("hello world", enc);
Konsol:Print(enc);      // aGVsbG8gd29ybGQ=

Var:String dec;
Hash:Base64Decode(enc, dec);
Konsol:Print(dec);      // hello world
