From 2e9c26cf9616fead92ec65eefc696bcf9761b996 Mon Sep 17 00:00:00 2001 From: Brad King Date: Wed, 16 Nov 2011 10:12:18 -0500 Subject: [PATCH] Add string(MD5) and string(SHA*) commands to compute hashes Provide a CMake-language binding to these cryptographic hashes. Add a string() command API for MD5, SHA1, SHA224, SHA256, SHA384, and SHA512. --- Source/cmStringCommand.cxx | 32 ++++++++++++++++++++++ Source/cmStringCommand.h | 5 ++++ Tests/CMakeTests/String-MD5-BadArg1.cmake | 1 + Tests/CMakeTests/String-MD5-BadArg2.cmake | 1 + Tests/CMakeTests/String-MD5-BadArg4.cmake | 1 + Tests/CMakeTests/String-MD5-Works.cmake | 2 ++ Tests/CMakeTests/String-SHA1-Works.cmake | 2 ++ Tests/CMakeTests/String-SHA224-Works.cmake | 2 ++ Tests/CMakeTests/String-SHA256-Works.cmake | 2 ++ Tests/CMakeTests/String-SHA384-Works.cmake | 2 ++ Tests/CMakeTests/String-SHA512-Works.cmake | 2 ++ Tests/CMakeTests/StringTest.cmake.in | 32 ++++++++++++++++++++++ 12 files changed, 84 insertions(+) create mode 100644 Tests/CMakeTests/String-MD5-BadArg1.cmake create mode 100644 Tests/CMakeTests/String-MD5-BadArg2.cmake create mode 100644 Tests/CMakeTests/String-MD5-BadArg4.cmake create mode 100644 Tests/CMakeTests/String-MD5-Works.cmake create mode 100644 Tests/CMakeTests/String-SHA1-Works.cmake create mode 100644 Tests/CMakeTests/String-SHA224-Works.cmake create mode 100644 Tests/CMakeTests/String-SHA256-Works.cmake create mode 100644 Tests/CMakeTests/String-SHA384-Works.cmake create mode 100644 Tests/CMakeTests/String-SHA512-Works.cmake diff --git a/Source/cmStringCommand.cxx b/Source/cmStringCommand.cxx index d239c063ad..f2f2681518 100644 --- a/Source/cmStringCommand.cxx +++ b/Source/cmStringCommand.cxx @@ -10,6 +10,8 @@ See the License for more information. ============================================================================*/ #include "cmStringCommand.h" +#include "cmCryptoHash.h" + #include #include @@ -36,6 +38,15 @@ bool cmStringCommand { return this->HandleReplaceCommand(args);
