std.crypto.hashes
The MD5, SHA-1, SHA-256, and SHA-512 hashes.
Md5, Sha1, Sha256, and Sha512, over mbedTLS: each one's Hash gives the hash of bytes, or of a String's bytes, at once, and an object of it adds them in turn. MD5 and SHA-1 are broken, since two inputs with one hash can be made, so they're only for checksums and the formats that ask for them; Sha256 and Sha512 are for the rest.

Types
Hasher
interface
Public Interface HasherWhat hashes bytes added to it in turn. Finish gives the hash of what was added, and starts again, empty.
Examples
Function HashOf(hasher: Hasher, parts: String[]): UInt8[]
For part In parts
hasher.Add(part)
End For
Return hasher.Finish()
End Function
Expect(HashOf(Sha256(), ["a", "b", "c"]) == Sha256.Hash("abc"))-
Adds
datato what it hashes. -
Adds
text's UTF-8 bytes to what it hashes. -
The hash of what was added, which starts it again, empty.
Md5
class
Public Class Md5 Implements HasherMD5's 16 bytes, only for checksums.
Examples
Expect(Hex.Encode(Md5.Hash("")) == "d41d8cd98f00b204e9800998ecf8427e")-
A new Md5, of nothing.

data. -
The MD5 of
text's UTF-8 bytes. -
Adds
datato what it hashes. -
Adds
text's UTF-8 bytes to what it hashes. -
The 16-byte MD5 of what was added, after which it starts again, empty.
Sha1
class
Public Class Sha1 Implements HasherSHA-1's 20 bytes, only for checksums and the formats that ask for it, like Git's.
Examples
Expect(Hex.Encode(Sha1.Hash("abc")) == "a9993e364706816aba3e25717850c26c9cd0d89d")-
A new Sha1, of nothing.
-
The SHA-1 of
data. -
The SHA-1 of
text's UTF-8 bytes. -
Adds
datato what it hashes. -
Adds
text's UTF-8 bytes to what it hashes. -
The 20-byte SHA-1 of what was added, after which it starts again, empty.
Sha256
class
Public Class Sha256 Implements HasherSHA-256's 32 bytes.
Examples
Expect(Hex.Encode(Sha256.Hash("abc")) ==
"ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad")
Local hasher = Sha256()
hasher.Add("ab")
hasher.Add("c".Bytes)
Expect(hasher.Finish() == Sha256.Hash("abc"))std/crypto/hashes.fb, line 141

text's UTF-8 bytes to what it hashes. -
The 32-byte SHA-256 of what was added, after which it starts again, empty.
Sha512
class
Public Class Sha512 Implements HasherSHA-512's 64 bytes.
Examples
Expect(Sha512.Hash("abc").Count == 64)std/crypto/hashes.fb, line 179
