Diffie-Hellman group size
Trigger The server uses a 2048-bit Diffie-Hellman group.
Context

Diffie-Hellman is mainly used so that two machines can compute a shared secret and so benefit from forward secrecy.

NIST recommends a group size of at least 1024 bits for legacy applications, 3072 bits for near term applications and 15360 for long term applications (NIST SP 800-57, Part 1, Rev. 3).

A

Security of hash function for certificate signature digest
Trigger The hash used for the certificate is SHA-256.
Context

NIST considers SHA-512 as the only hash algorithm providing security for long-term use. Algorithms SHA-256 and SHA-384 are acceptable for near-term use and SHA-1 should not be used (NIST SP 800-57, Part 1, Rev. 3).

Support for DES cipher
Trigger The server doesn't support any cipher suites containing the DES cipher.
Context

DES is a cipher with an effective key length of 56 bits, which is considered unsuitable by NIST even for legacy use (NIST SP 800-57, Part 1, Rev. 3).

Diffie-Hellman group size
Trigger The server uses a 2048-bit Diffie-Hellman group.
Context

Diffie-Hellman is mainly used so that two machines can compute a shared secret and so benefit from forward secrecy.

NIST recommends a group size of at least 1024 bits for legacy applications, 3072 bits for near term applications and 15360 for long term applications (NIST SP 800-57, Part 1, Rev. 3).

Security of hash function for certificate signature digest
Trigger The hash used for the certificate is SHA-256.
Context

NIST considers SHA-512 as the only hash algorithm providing security for long-term use. Algorithms SHA-256 and SHA-384 are acceptable for near-term use and SHA-1 should not be used (NIST SP 800-57, Part 1, Rev. 3).

Support for DES cipher
Trigger The server doesn't support any cipher suites containing the DES cipher.
Context

DES is a cipher with an effective key length of 56 bits, which is considered unsuitable by NIST even for legacy use (NIST SP 800-57, Part 1, Rev. 3).

Certificate RSA key length
Trigger The server uses a 2048-bit RSA key.
Context

NIST recommends a length of at least 1024 bits for legacy applications, 2048 bits for near term applications and 15360 bits for long term applications (NIST SP 800-57, Part 1, Rev. 3).
