# Objective-C-RSA

Doing RSA encryption with Objective-C iOS

## If you have the same qustion as mine: [iOS Objective-C RSA encrypt with only public key and descrypt with PHP](http://www.ideawu.com/blog/post/132.html)

## Usage

	#import "RSA.h"

	

	NSString *pubkey = @"-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDDI2bvVLVYrb4B0raZgFP60VXY\ncvRmk9q56QiTmEm9HXlSPq1zyhyPQHGti5FokYJMzNcKm0bwL1q6ioJuD4EFI56D\na+70XdRz1CjQPQE3yXrXXVvOsmq9LsdxTFWsVBTehdCmrapKZVVx6PKl7myh0cfX\nQmyveT/eqyZK1gYjvQIDAQAB\n-----END PUBLIC KEY-----";

	NSString *privkey = @"-----BEGIN PRIVATE KEY-----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\n5xd0pcy9O2DOeso=\n-----END PRIVATE KEY-----";

	

	NSString *encrypted = [RSA encryptString:@"hello world!" publicKey:pubkey];

	NSLog(@"encrypted: %@", encrypted);

	NSString *decrypted = [RSA decryptString:encrypted privateKey:privkey];

	NSLog(@"decrypted: %@", decrypted);

__Notice: iOS 10 requires Keychain Entitlements__
