获取MD5和SHA-1

我正在寻找一些在我的iPhone应用程序获取MD5和SHA-1的帮助。 有谁能给我一个如何得到这些想法？

Answer 1

#include <CommonCrypto/CommonDigest.h> -(NSString*) sha1:(NSString*)input { NSData *data = [input dataUsingEncoding: NSUTF8StringEncoding]; uint8_t digest[CC_SHA1_DIGEST_LENGTH]; CC_SHA1(data.bytes, data.length, digest); NSMutableString* output = [NSMutableString stringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2]; for(int i = 0; i < CC_SHA1_DIGEST_LENGTH; i++) [output appendFormat:@"%02x", digest[i]]; return output; } - (NSString *) md5:(NSString *) input { const char *cStr = [input UTF8String]; unsigned char digest[CC_MD5_DIGEST_LENGTH]; CC_MD5( cStr, (CC_LONG)strlen(cStr), digest ); // This is the md5 call NSMutableString *output = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2]; for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++) [output appendFormat:@"%02x", digest[i]]; return output; }
