Report
Hostname: | close Doesn't match Common Name or/and SANs |
Expired: | done No (10 days till expiration) |
Public Key: | close RSA key size is too small, current industry standard for RSA keys is 2048 bits |
Trusted: | close The end-entity certificate is self-signed |
Self-Signed: | close Yes, the end-entity certificate is self-signed |
Chain Issues: | close The chain doesn't contain any intermediate certificates |
Weak signatures: | done No, certificates sent by the server were not signed utilizing a weak hash function |
