iOS Rsa加解密

近期公司项目需要用到Rsa加解密,特此编写了此demo

// RsaEncrypt.h

// RsaEncrypt

// Created by ZhangNing on 2018/5/16.

#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.
