WebDec 2, 2016 · The AES standard (FIPS 197) is silent on how nonstandard key sizes are handled. The AES implementations I've seen all reject nonstandard key sizes with an error; however a higher level crypto implementation (that does more than 'just AES') might choose to provide more services (depending on the job it is designed for). WebAug 21, 2024 · The problem is number 1: you are passing the password instead of the key. AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from …

WebIn fact we can, it is not common, because when NIST did choose AES candidates, they limit block size to 128 bit, and key to 128, 192, or 256 bits. For me this limitation is pure artificial and created just to make some sort of standard approach. We won't speculate on reason they decide to do so. WebApr 14, 2024 · GCM uses a key size of 128, 192 or 256 bits according to AES, and the block size of 128 bits. The initialization vector (iv)is restricted to lengths less than or equal to 264-1 in multiples of 8. You cannot use a symmetric cipher with a smaller block size because GCM was designed for 128-bit ciphers. can student loans take my house
