RIPEMD Hash a String

See more Encryption Examples

Demonstrates how to RIPEMD hash a string using RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320. Objective-C

#import <CkoCrypt2.h>
#import <NSString.h>

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

CkoCrypt2 *crypt = [[CkoCrypt2 alloc] init];

NSString *content = @"abcdefghijklmnopqrstuvwxyz";

//  The desired output is a hexidecimal string:
crypt.EncodingMode = @"hex";

//  Set the hash algorithm:
crypt.HashAlgorithm = @"ripemd128";

NSString *hashStr = 0;
hashStr = [crypt HashStringENC: content];

NSLog(@"%@",hashStr);

//  The output is:
//  FD2AA607F71DC8F510714922B371834E

crypt.HashAlgorithm = @"ripemd160";
hashStr = [crypt HashStringENC: content];
NSLog(@"%@",hashStr);

//  The output is:
//  F71C27109C692C1B56BBDCEB5B9D2865B3708DBC

crypt.HashAlgorithm = @"ripemd256";
hashStr = [crypt HashStringENC: content];
NSLog(@"%@",hashStr);

//  The output is:
//  649D3034751EA216776BF9A18ACC81BC7896118A5197968782DD1FD97D8D5133

crypt.HashAlgorithm = @"ripemd320";
hashStr = [crypt HashStringENC: content];
NSLog(@"%@",hashStr);

//  The output is:
//  CABDB1810B92470A2093AA6BCE05952C28348CF43FF60841975166BB40ED234004B8824463E6B009
