WebAug 1, 2024 · AES, RSA and DH keys are all used for different purposes. When creating a protocol or when configuring your software it does make sense to use relating key sizes. So you would use symmetric keys of 128 bit or over, RSA keys of 3072 bits or over and ECC keys (and hashes) of 256 bits or over to achieve an overall strength of 128 bits. WebIn order to create a Cipher object, the application calls the Cipher's getInstance method, and passes the name of the requested transformation to it. Optionally, the name of a …
