Question

我试图在钥匙串中添加密钥，然后用它加密数据。

NSData* peerTag = [@"Test PublicKey" dataUsingEncoding:NSUTF8StringEncoding];

NSDictionary * peerPublicKeyAttr = [NSDictionary dictionaryWithObjectsAndKeys:
 (__bridge id)kSecClassKey, kSecClass,
 (__bridge id)kSecAttrKeyTypeRSA, kSecAttrKeyType,
 (__bridge id)kSecAttrKeyClassPublic, kSecAttrKeyClass,
 peerTag, kSecAttrApplicationTag,
 testPubKey, kSecValueData,
 kCFBooleanTrue, kSecReturnPersistentRef,
                                    nil];

OSStatus sanityCheck = noErr;
sanityCheck = SecItemDelete((__bridge CFDictionaryRef) peerPublicKeyAttr);
SecKeyRef persistPeer = NULL;
sanityCheck = SecItemAdd((__bridge CFDictionaryRef)peerPublicKeyAttr, (CFTypeRef *)&persistPeer);


NSData* passwordData = [@"password" dataUsingEncoding:NSUTF8StringEncoding];
NSData* encryptedPass = [[Methods sharedCenter]encrypt:passwordData usingKey:persistPeer];

size_t cipherBufferSize = SecKeyGetBlockSize(persistPeer);

SecKeyGetBlockSize(key);会导致EXC_BAD_ACCESS代码= 1。

我之前没有使用过这个，所以我不确定会导致这个错误的原因。我在这做错了什么？

Answer 1

你在哪里定义了“钥匙”？检查它是否真的存在：if（key）{... 我认为密钥没有定义或是NULL？

SecKeyGetBlockSize（）上的EXC_BAD_ACCESS代码= 1
