本项目将libsodium进行了封装，用于
更多封装将很快推出。
您想在Keybase上从事加密工作吗？我们正在招聘。
如果您正在寻找其他与libsodium无关的加密（曾在此处出现），请参阅NACrypto。
pod "NAChloride"您应该在应用启动时调用NAChlorideInit()进行初始化。这是线程安全的，多次调用会被忽略。我们也会自动调用此方法作为一项安全措施。
NAChlorideInit();请参阅安全内存分配。
NASecureData *secureData = [NASecureData secureReadOnlyDataWithLength:length completion:^(void *bytes, NSUInteger length) {
// Set the bytes here. After this it will be read-only.
}];
// After the block executes, secureData is read-only. You can set it to no access (or read/write).
// If you set it to no access and secureData.bytes is accessed, it will SIGABRT. For example,
// secureData.protection = NASecureDataProtectionNoAccess;一些类如NASecretBox、NABox和NAAEAD提供启用安全内存的选项（在解密时）。
NASecureData是NSMutableData的子类，以兼容性和与其他API的使用。
请参阅生成随机数据。
NSData *data = [NARandom randomData:32]; // 32 bytes of random data
NSData *data = [NARandom randomSecureReadOnlyData:32]; // 32 bytes of random, secure, read-only data使用共享密钥和nonce加密和验证消息。
