近期公司项目需要用到Rsa加解密,特此编写了此demo

#import
@interfaceRsaEncrypt :NSObject
typedefNS_ENUM(OSStatus,RSA_SATAUS){
RSA_SUCCESS =0,
RSA_FAILED =1<<1,
RSA_GET_PUBLICKEY_FAILED =1<<2,
RSA_GET_PRIVATEKEY_FAILED =1<<3
};
//类方法,初始化设置公私钥Tag
+ (instancetype)sharedInstancePrivateTag:(NSData*)privateTag publicTag:(NSData*)publicTag;
//临时创建后临时更改公私钥tag
- (void) setPrivateTag:(NSData*)privateTag publicTag:(NSData*)publicTag;
//create Rsa generateKeys publicKey and privateKey
- (RSA_SATAUS)createRSA_generate_keys;
//encrypt someDataString use privateKey
- (RSA_SATAUS)encryptBeforeEncryptDataIn:(NSData*)encryptDataIn EncryptDataOut:(NSData**)encryptDataOut;
//decode SomeEncryptData use publicKey
- (RSA_SATAUS)decodeBeforeEncryptDataIn:(NSData*)encryptDataIn DecodeRncryptDataOut:(NSData**)decodeEncryptDataOut;
//del public and private keys Use KyesTag;
- (RSA_SATAUS)deleteRsaKeys;
@end
此demo 对类进行封装,封装系统加解密方法,实现数据的加解密.
公钥私钥存储在keychain中,方法调用简单详情参照demo来完成.
如有错误请批评指出.
