I also checked my server certificate, it is using SHA-256 and a key length of 2048 bit so this should be fine (additionally, if the certificate was weak, setting NSExceptionRequiresForwardSecrecy to false should not solve the problem?).

The strange thing about this is that NSExceptionRequiresForwardSecrecy solved the issue, since as far as I know this is all about the used cipher suite and not about the certificate. Also, I double checked that my certificate fulfills the ATS requirements (no SHA-1, at least 2048bit), so in theory it should be possible to connect. The error _kCFStreamErrorCodeKey=-9802 (errSSLFatalAlert) is also not quite helpful.

The 'Classic 2048 Offline Game' is a compact (only 1MB) Chrome extension that lets you play the addictive number-merging game, 2048, offline on any Chrome tab. Simply install the extension, click the 2048 icon on the toolbar, and enjoy your game without needing the internet. The extension merges any two tiles with the same number into one, offering an engaging gaming experience.

Because the consequences of a compromised root CA are so great (up to and including the need to re-issue each and every certificate in the PKI), all root CAs must be kept safe from unauthorized access. A common method to ensure the security and integrity of a root CA is to keep it in an offline state. It is only brought online when needed for specific, infrequent tasks, typically limited to the issuance or re-issuance of certificates authorizing intermediate CAs.

A drawback to offline operation is that hosting of a certificate revocation list by the root CA is not possible (as it is unable to respond to CRL requests via protocols such as HTTP, LDAP or OCSP). However, it is possible to move certificate validation functionality into a dedicated validation authority authorized by the offline root CA.

To better understand how an offline root CA can greatly improve the security and integrity of a PKI, it is important to realize that a CRL is specific to the CA which issued the certificates on the list. Therefore, each CA (root or intermediate) is only responsible for tracking the revocation of certificates it alone has issued.

2048 game offline, simple yet very addictive game which you can play in most of devices. Join the numbers and get to the 2048 tile. But it is not the limit, you can do even more after reaching 2048 in a tile.

If you are like me you have lost many hours playing 2048 on your phone. This game helped me keep my sanity back in 2014 when it seemed like I was flying somewhere every week. I would play this game in the airport waiting to board and on the plane when I was just too tired to focus on work.

Now when I do a select * from master..sysdatabases than the status is 65536 (the database is online) now when I bring the database offline the status changes to 66048, from the information I've found at the Internet the code must be 512.

Each key has its own purpose: Signature, Encryption, and Authentication. Smartcards typically have limitation on key sizes, so I select 2048 as a widely supported size. Expert mode is required to generate authentication subkeys.

Okay, I tried it. The Yubikey Neo supports key up to 2048 bits, and it supports key imports since the version 1.0.5 of its PGP applet. In my case, I had to upgrade it, which is not really trivial since it relies on pieces of software I had to compile, and that suffer from a strange bug (gpshell does not look for libraries in /usr/local/lib, where libglobalplatform gets installed by default).

AWS KMS provides simple APIs that you can use to securely generate, store, and manage keys, including RSA key pairs inside hardware security modules (HSMs). Key pairs are generated within FIPS 140-2 validated HSMs that are managed by AWS. You can then use these private keys through APIs to do actions such as decrypt ciphertexts, meaning that plaintext private keys never leave the HSM, which provides assurances of privacy for the private key. Additional APIs allow a customer to retrieve a plaintext copy of the corresponding public key, which allows disconnected or offline uses of RSA public keys.

A key drawback to asymmetric cryptography is the fact that you cannot encrypt large pieces of data. When you have a 2048-bit RSA key pair and encrypt something by using the cipher RSAES_OASEP_SHA_256, the largest amount of data that you can encrypt is 190 bytes.

To create a key pair in AWS KMS, use the CreateKey API. For this example, you will create an RSA key pair with RSA_2048 for the CustomerMasterKeySpec parameter and ENCRYPT_DECRYPT for the KeyUsage parameter in the AWS CLI. This post uses 2048-bit keys, but note that AWS KMS allows larger key sizes. The CLI will return a KeyId value that uniquely identifies the KMS key in your account, which you should take note of.

In this post, you learned how to combine AWS KMS asymmetric key pairs with locally created symmetric keys to encrypt and share data that exceeds 190 bytes, without storing a secret on a client device. By taking advantage of the RSA cryptosystem for offline encryption, you can reduce the exposure of plaintext data or secrets to devices outside of your control, and without having to complete complex key exchanges. By using the steps in this solution, you can more securely share large amounts of data, such as update files or configuration settings. To learn more about the asymmetric keys feature of AWS KMS, refer to the AWS KMS Developer Guide. If you have questions about the asymmetric keys feature, interact with us through AWS re:Post.

You can download the public key of your SM2 key pair for use in offline operations, that is, operations outside of AWS KMS. However, when using your SM2 public key offline, you may need to manually perform extra conversions and calculations. SM2DSA operations may require you to provide a distinguishing ID or calculate a message digest. SM2PKE encrypt operations may require you to convert the raw ciphertext output to a format AWS KMS can accept.

However, if you are generating a message digest outside of AWS, you can specify your own distinguishing ID, then pass the message digest, MessageType:DIGEST, to AWS KMS to sign. To do this, change the DEFAULT_DISTINGUISHING_ID value in the SM2OfflineOperationHelper class. The distinguishing ID you specify can be any string up to 8,192 characters long. After AWS KMS signs the message digest, you need either the message digest or the message and the distinguishing ID used to compute the digest to verify it offline.

To generate a message digest offline that you can use for offline verification, or that you can pass to AWS KMS to sign, use the calculateSM2Digest method. The calculateSM2Digest method generates a message digest with the SM3 hashing algorithm. The GetPublicKey API returns your public key in binary format. You must parse the binary key into a Java PublicKey. Provide the parsed public key with the message. The method automatically combines your message with the default distinguishing ID, 1234567812345678, but you can set your own distinguishing ID by changing the DEFAULT_DISTINGUISHING_ID value.

To verify a signature offline, use the offlineSM2DSAVerify method. The offlineSM2DSAVerify method uses the message digest calculated from the specified distinguishing ID, and original message you provide to verify the digital signature. The GetPublicKey API returns your public key in binary format. You must parse the binary key into a Java PublicKey. Provide the parsed public key with the original message and the signature you want to verify. For more details, see Offline verification with SM2 key pairs.

To encrypt plaintext offline, use the offlineSM2PKEEncrypt method. This method ensures the ciphertext is in a format AWS KMS can decrypt. The offlineSM2PKEEncrypt method encrypts the plaintext, and then converts the raw ciphertext produced by SM2PKE to the ASN.1 format. The GetPublicKey API returns your public key in binary format. You must parse the binary key into a Java PublicKey. Provide the parsed public key with the plaintext that you want to encrypt.

Higher texture sizes come at the cost of more memory usage and slower rendering times.

If you are offline rendering then these issues are less predominant, but for real time rendering such as games then it is by far one of the largest limitations.
