JYBlockChainSDK

JYBlockChainSDK是一个区块链钱包SDK，可以创建钱包，生成助记词，生成钱包地址，以及wif私钥
本SDK 需要依赖OpenSSL

安装

pod 'JYBlockChainSDK'  
pod "OpenSSL-Universal"    
pod install  

如何使用

Example里面的 JYViewController 有部分展示   
import "JYBlockChainSDK/JYBlockChainSDK.h"  

//创建一个钱包并生成助记词
NSString *mnemonicString = [JYBlockChainMain generateMnemonicString:Entropy128];
//助记词为idea talent month depth what cave tuna liar book corn alone increase
NSLog(@"助记词为%@", mnemonicString);

//获取master密钥
//先获取种子
NSData *seed = [JYBlockChainMain generateSeedFromMnemonicString:mnemonicString passphrase:@""];
//通过种子拿到master密钥
JYBlockChainKey*masterKey =[JYBlockChainMain generateKeyfromSeed:seed];
NSString *seedStr = [JYBlockChainTools my_hexstringFromData:seed];
NSString *privateKey = [JYBlockChainTools my_hexstringFromData:masterKey.privateKey];
NSString *compressedPublicKey = [JYBlockChainTools my_hexstringFromData:masterKey.compressedPublicKey];
NSString *uncompressedPublicKey = [JYBlockChainTools my_hexstringFromData:masterKey.uncompressedPublicKey];
