The padlock is a visual indication that your connection to the website has been secured using HTTPS.
This keeps your data secure from hackers trying to steal account details.
Links to phishing sites are often sent via email.
Malware is a catch-all term for Malicious software it includes viruses, worms, ransomware, and more.
In the security panel overview, there are three sections of information, Certificate, Connection, and Resources.
The encryption algorithm should ideally say TLS 1.2 or TLS 1.3.
TLS, or Transport Level Security, is the standard for negotiating encryption configurations.
TLS versions 1.3 and 1.2 are the current standards and are considered secure.
Tip: Deprecated means that their use is being discouraged and steps are being taken to remove support.
The predecessors to TLS were SSLv3 and SSLv2.
The next value is the key exchange algorithm.
This is used to securely negotiate the encryption key to be used with the encryption algorithm.
Explicitly not supporting access to this information in the internet tool means that it cant be compromised by accident.
The final value in the Connection section is the cipher suite used to encrypt the connection.
Once again there are far too many to name.
Tip: 128 or 256 bits are the most common levels of cryptographic security.
They mean that there 128 or 256 bits of randomness making up the encryption key being used.
Thats 2^128 possible combinations, or two multiplied by itself 128 times.
As with all exponentials, the numbers get very big, very fast.
It is unimaginably difficult to correctly guess an encryption key, even with multiple supercomputers and centuries of time.
Tip: Certificate Transparency is a protocol used to counter some historical abuses of the certificate issuing process.
