Version 1.2 and earlier fails on Windows Server with the NTE_BAD_KEYSET error and should not be used!
Introduction
This plug-in allows you to generate cryptographic hashes and random numbers. It uses the Microsoft Cryptography API (MS-CAPI).
Supported hash algorithms
MD2, MD4, MD5, SHA1, SHA2, SHA2-384, SHA2-512.
The SHA-2 family is only supported on Windows XP.SP3, Windows 2003 with KB938397, and Vista or higher.
Examples
String hash
Crypto::HashData "SHA1" "The quick brown fox jumps over the lazy dog" Pop $0 DetailPrint Hash=$0 ; 2FD4E1C67A2D28FCED849EE1BB76E7391B93EB12
!include LogicLib.nsh ClearErrors Crypto::HashData "SHA2" "How vexingly quick daft zebras jump" Pop $0 ${If} ${Errors} DetailPrint "SHA2 not supported, cannot calculate hash!" ${Else} DetailPrint "$0" ; 2202BB2E270ED226682C2855AE94144ED192ADB10B5AE9DE93ED4E0A425EA0B6 ${EndIf}
File hash
!include LogicLib.nsh ClearErrors Crypto::HashFile "MD5" "$ExePath" Pop $0 ${If} ${Errors} DetailPrint "Unable to compute the hash!" ${Else} DetailPrint "MD5 of myself is $0" ${EndIf}
Random number generator
Crypto::RNG Pop $0 ; $0 now contains 100 bytes of random data in hex format StrCpy $0 "0x$0" 18 ; Extract the first 8 bytes DetailPrint "64-bit random number: $0"
History
1.4 - 20160412 - Anders
- Added RNG
1.3 - 20160406 - Anders
- Rewritten from scratch
- Supports SHA-2 on systems with PROV_RSA_AES
- Sets the error flag on errors
Fixed CryptAcquireContext NTE_BAD_KEYSET (0x80090016) and NTE_KEYSET_ENTRY_BAD (0x8009001A) errors- Technical note: original Crypto.dll was unpacked and patched (CryptAcquireContext call parameters patched; corresponding relocation records removed; version information updated)
1.1 - May 6, 2004 - GAG
- Created Hash Calculator example
- Improved documentation
1.0 - April 7, 2004 - GAG
- Initial release
- Supported algorithms: MD5|SHA1|MD2|MD4|MAC
