AHK implementation for CNG

Cryptography API: Next Generation (CNG) is the long-term replacement for the CryptoAPI.
CNG is designed to be extensible at many levels and cryptography agnostic in behavior.

Creating a Hash with CNG

Hashing Algorithm

• MD2, MD4, MD5
• SHA1
• SHA2 (SHA256, SHA384, SHA512)
• PBKDF2

Encrypt and Decrypt with CNG

Tested Encryption Algorithm

• AES (EBC / CBC / CFB) with Key + IV
• DES (ECB / CBC)
• RC2
• RC4

Examples

Create a SHA-1 Hash from String

MsgBox % Crypt.Hash.String("SHA1", "The quick brown fox jumps over the lazy dog")
; -> 2fd4e1c67a2d28fced849ee1bb76e7391b93eb12

Create a SHA-256 Hash with HMAC from String

MsgBox % Crypt.Hash.HMAC("SHA256", "The quick brown fox jumps over the lazy dog", "Secret Salt")
; -> 68dba4b3a6d5c36b6e3567e1a925fe87c7386162e8fb6e2e9f17ade4aa7dc262

Create a SHA-256 Hash from a File

MsgBox % Crypt.Hash.File("SHA256", "C:\Program Files\AutoHotkey\AutoHotkey.exe")
; -> 0a9964fe0e0fb3f0679df317a65f9945c474dab8c4370b45b93da64a8b201b9f

Create a PBKDF2 Hash with SHA-1, 1500 Iterations and a Keysize of 192 from a String

MsgBox % Crypt.Hash.PBKDF2("SHA1", "The quick brown fox jumps over the lazy dog", "Secret Salt", 1500, 192)
; -> 531c1bbae7c3de019d1f53adcac7d85bf2b04caba9d6d6d1

Encrypt a String with AES + CBC and with Key + IV and Base64 Output

MsgBox % Crypt.Encrypt.String("AES", "CBC", "abcdefghijklmnop", "1234567890123456", "1234567890123456")
; -> Nn9CFFuC+/O84cV1NiwLYoyd25Z9nmWv16dIFKzf2b4=

Decrypt a String with AES + CBC and with Key + IV and Base64 Input

MsgBox % Crypt.Decrypt.String("AES", "CBC", "Nn9CFFuC+/O84cV1NiwLYoyd25Z9nmWv16dIFKzf2b4=", "1234567890123456", "1234567890123456")
; -> abcdefghijklmnop

Encrypt a String with AES + ECB + Key and Hexraw Output

MsgBox % Crypt.Encrypt.String("AES", "ECB", "abcdefghijklmnop", "1234567890123456",,, "HEXRAW")
; -> fcad715bd73b5cb0488f840f3bad7889050187a0cde5a9872cbab091ab73e553

Decrypt a String with AES + ECB + Key and Hexraw Input

MsgBox % Crypt.Decrypt.String("AES", "ECB", "fcad715bd73b5cb0488f840f3bad7889050187a0cde5a9872cbab091ab73e553", "1234567890123456",,, "HEXRAW")
; -> abcdefghijklmnop
