使用方法先导入头文件 #import "SHA1.h"

//SHA1测试NSString* sh1=[SHA1 getSha1String:@"123"];NSLog(@"sh1=%@  长度：%d",sh1,[sh1 length]);NSString * sh2=[SHA1 getSha256String:@"123"];NSLog(@"sh2=%@  长度：%d",sh2,[sh2 length]);

自建NSObject子类命名SHA1

SHA1.h

#import 
     
      @interface SHA1 : NSObject+ (NSString *)getSha1String:(NSString *)srcString;+ (NSString *)getSha256String:(NSString *)srcString;+ (NSString *)getSha384String:(NSString *)srcString;+ (NSString *)getSha512String:(NSString*)srcString;@end

SHA1.m

#import "SHA1.h"#import 
     
      #import 
      
       @implementation SHA1//sha1加密方式+ (NSString *)getSha1String:(NSString *)srcString{    const char *cstr = [srcString cStringUsingEncoding:NSUTF8StringEncoding];    NSData *data = [NSData dataWithBytes:cstr length:srcString.length];    uint8_t digest[CC_SHA1_DIGEST_LENGTH];    CC_SHA1(data.bytes, data.length, digest);    NSMutableString* result = [NSMutableString stringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2];    for(int i = 0; i < CC_SHA1_DIGEST_LENGTH; i++) {        [result appendFormat:@"%02x", digest[i]];    }    return result;}//sha256加密方式+ (NSString *)getSha256String:(NSString *)srcString {    const char *cstr = [srcString cStringUsingEncoding:NSUTF8StringEncoding];    NSData *data = [NSData dataWithBytes:cstr length:srcString.length];    uint8_t digest[CC_SHA256_DIGEST_LENGTH];    CC_SHA1(data.bytes, data.length, digest);    NSMutableString* result = [NSMutableString stringWithCapacity:CC_SHA256_DIGEST_LENGTH * 2];    for(int i = 0; i < CC_SHA256_DIGEST_LENGTH; i++) {        [result appendFormat:@"%02x", digest[i]];    }    return result;}//sha384加密方式+ (NSString *)getSha384String:(NSString *)srcString {    const char *cstr = [srcString cStringUsingEncoding:NSUTF8StringEncoding];    NSData *data = [NSData dataWithBytes:cstr length:srcString.length];    uint8_t digest[CC_SHA384_DIGEST_LENGTH];    CC_SHA1(data.bytes, data.length, digest);    NSMutableString* result = [NSMutableString stringWithCapacity:CC_SHA384_DIGEST_LENGTH * 2];    for(int i = 0; i < CC_SHA384_DIGEST_LENGTH; i++) {        [result appendFormat:@"%02x", digest[i]];    }    return result;}//sha512加密方式+ (NSString *)getSha512String:(NSString*)srcString {    const char *cstr = [srcString cStringUsingEncoding:NSUTF8StringEncoding];    NSData *data = [NSData dataWithBytes:cstr length:srcString.length];    uint8_t digest[CC_SHA512_DIGEST_LENGTH];    CC_SHA512(data.bytes, data.length, digest);    NSMutableString* result = [NSMutableString stringWithCapacity:CC_SHA512_DIGEST_LENGTH * 2];    for(int i = 0; i < CC_SHA512_DIGEST_LENGTH; i++)        [result appendFormat:@"%02x", digest[i]];    return result;}@end
