SynCrypto Stream Encryption/Decryption
Hi.
I have a binary data encrypted with AES loaded into a stream and I have the string value of the Key and Vector. How I can decrypt and encrypt back that stream using the key and vector values?

Re: SynCrypto Stream Encryption/Decryption
It depends on the AES key size, the AES block mode, the padding used, and how the strings have been hashed/encoded.
But there's no standard method? Because there's some tools which can decrypt this binary data only with this two infos: key and Vector.

Re: SynCrypto Stream Encryption/Decryption
Key size, block mode, padding, hashing ARE the standards. 
https://en.wikipedia.org/wiki/Advanced_ … n_Standard
https://en.wikipedia.org/wiki/Block_cip … _operation
https://en.wikipedia.org/wiki/Padding_(cryptography)
https://en.wikipedia.org/wiki/Cryptogra … h_function
And any change on those parameter will change the whole encryption method, and change the results, for sure.
