Dear AutoIt communities, I wish to perform SHA-256 hashing with AutoIt. I noticed Help File shows the use of MD2, MD4, MD5, SHA1. To my knowledge, all of these aren't cryptographically secure anymore and SHA-2 (SHA-256, SHA-384, SHA-512) is the way to hash passwords. I poked around Crypt.au3 and found SHA-2 constants are commented out. Why is this? I'm using latest public release, v 3.3.14.2 ; #CONSTANTS# =================================================================================================================== Global Const $PROV_RSA_FULL = 0x1 Global Const $PROV_RSA_AES = 24 Global Const $CRYPT_VERIFYCONTEXT = 0xF0000000 Global Const $HP_HASHSIZE = 0x0004 Global Const $HP_HASHVAL = 0x0002 Global Const $CRYPT_EXPORTABLE = 0x00000001 Global Const $CRYPT_USERDATA = 1 Global Const $CALG_MD2 = 0x00008001 Global Const $CALG_MD4 = 0x00008002 Global Const $CALG_MD5 = 0x00008003 Global Const $CALG_SHA1 = 0x00008004 ; Global Const $CALG_SHA_256 = 0x0000800c ; Global Const $CALG_SHA_384 = 0x0000800d ; Global Const $CALG_SHA_512 = 0x0000800e Global Const $CALG_3DES = 0x00006603 Global Const $CALG_AES_128 = 0x0000660e Global Const $CALG_AES_192 = 0x0000660f Global Const $CALG_AES_256 = 0x00006610 Global Const $CALG_DES = 0x00006601 Global Const $CALG_RC2 = 0x00006602 Global Const $CALG_RC4 = 0x00006801 Global Const $CALG_USERKEY = 0 Global Const $KP_ALGID = 0x00000007 I thought this could be compatibility issues, and older Windows doesn't support SHA-2. Without knowing what I am doing, MSDN help appears to say SHA256 is available since Windows Platform 10 (https://msdn.microsoft.com/en-us/library/system.security.cryptography.sha256(v=vs.110).aspx) However other sources said SHA-2 has been supported since Win XP SP 3. What is happening? How can I implement SHA-2 with confidence that it will work on Win XP? Unfortunately I do not have an older computer or virtual PC to test it out. I'm running latest Windows 10 and SHA-256, SHA-384, SHA-512 all works fine. (If you like to try on your machine, I've attached the help file hashing example with SHA-2 algo added) Thank you yet again Crash sdfsdaf.au3
