Maximum length of 4096.Ĭhecks if your request will succeed. To get the alias name and alias ARN, use ListAliases. To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. TheĪlgorithm must be compatible with the KMS key spec. If you specify an asymmetric KMS key, you must also specify the encryption algorithm. For more information, seeĪWS Key Management Service Developer Guide. Otherwise, the request toĭecrypt fails with an InvalidCiphertextException. If you specify anĮncryptionContext when encrypting data, you must specify the same encryptionĬontext (a case-sensitive exact match) when decrypting the data. If you use a symmetric encryption KMS key, you can use an encryption context to addĪdditional security to your encryption operation. The GenerateDataKeyĪnd GenerateDataKeyPair operations return a plaintext data key and an

You can use a symmetric orĪsymmetric KMS key with a KeyUsage of ENCRYPT_DECRYPT. BUT it will take much longer than that for process tech and buildout of the panels, and the infrastructure to get it all working, so I would still say at least a few centuries, probably under 2000 years.Encrypts plaintext of up to 4,096 bytes using a KMS key. If we really decide to cover all land mass with solar panels to do the job, we can get maybe 4X more power, and get it done in 40 years. We will hit the limits of lithography, but I would assume we can improve our compute performance another 128-times in that time period, and maybe improve solar efficiency by double, so lets say 136 years. That means we could test approximately $5 \cdot 10^$ seconds required to fully process a 128-bit key, or over 34000 years. There special purpose hardware is used and it's for SHA-256, this makes it not directly usable, but it should be close. Let's assume we can test as many keys as the current hashrate of the bitcoin network. The estimation for half the known key would therefore be $~3.6$ seconds.īut to brute force a $128$ bit key, we get this estimate: Since then, the bitcoin hashrate almost tripled (it's used in the estimation, as below). I wrote a similar answer in the past, where the assumption was half the key is known.
