我正在使用以下代码创建密钥

let tag = "com.example.keys.mykey".data(using: .utf8)!
let attributes: [String: Any] =
[kSecAttrKeyType as String:            kSecAttrKeyTypeECSECPrimeRandom,
 kSecAttrKeySizeInBits as String:      256,
 kSecPrivateKeyAttrs as String:
    [kSecAttrIsPermanent as String:    true,
     kSecAttrApplicationTag as String: tag]]
guard let privateKey = SecKeyCreateRandomKey(attributes as CFDictionary, &error) else {
throw error!.takeRetainedValue() as Error}

使用获取公钥

let publicKey = SecKeyCopyPublicKey(privateKey)
