Diffie-hellman key size

The key size is the same as the authentication certificate, but must be 1024 - 2048 bits, inclusively.

3. What is key size in RSA?

What is the recommended DH key size?

the key size (DH parameter) in the Diffie-Hellman key exchange method is set to 1024 bits or less. As for PCIDSS requirement, it is recommended to set 2048 bits or more for the DH parameter.

What is the key length of Diffie-Hellman Group 2?

The exchanged keying material that is shared by the two computers can be based on 768, 1024, or 2048 bits of keying material, known as Diffie-Hellman groups 1, 2, and 2048, respectively.

What is key size in RSA?

For RSA keys, the minimum size for clear RSA keys and secure RSA keys on the public key data set (PKDS) is 512 bits. The minimum size for secure RSA keys on the token key data set (TKDS) is 1024 bits and the size must be a multiple of 256.
