I have recently upgraded to windows 11, using IE 11. when I go to a browser page,, all that shows the address bar, I always have to maximise the page every time I want to change browser pages.. do you know why? thank you john ayton
You must obtain a security certificate as a part of enabling HTTPS for your site. The certificate is issued by a certificate authority (CA), which takes steps to verify that your web address actually belongs to your organization, thus protecting your customers from man-in-the-middle attacks. When setting up your certificate, ensure a high level of security by choosing a 2048-bit key. If you already have a certificate with a weaker key (1024-bit), upgrade it to 2048 bits. When choosing your site certificate, keep in mind the following:
Using a message digest enhanced with a key (so only a key-holder can check the MAC). The HMAC construction used by most TLS cipher suites is specified in RFC 2104 (SSL 3.0 used a different hash-based MAC).
Any kind of business website (or any sites that send and receive sensitive customer information) will hugely benefit from an Extended Validation SSL certificate. Extended Validation gives your customers extra peace of mind by not only encrypting your web pages, but also by adding your company name to the green padlock area in the address bar of the browser. To get this additional authentication, some details of your website and business (such as location and company number) are verified by the SSL certificate issuing body. This means your customers know beyond any doubt you are who you say you are and that their personal data is safe.
Jump up ^ Safari uses the operating system implementation on Mac OS X, Windows (XP, Vista, 7) with unknown version, Safari 5 is the last version available for Windows. OS X 10.8 on have SecureTransport support for TLS 1.1 and 1.2 Qualys SSL report simulates Safari 5.1.9 connecting with TLS 1.0 not 1.1 or 1.2
Historically, HTTPS connections were primarily used for payment transactions on the World Wide Web, e-mail and for sensitive transactions in corporate information systems. Since 2018 HTTPS is more used on websites than the original non-secure HTTP; protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
A client sends a ClientHello message specifying the highest TLS protocol version it supports, a random number, a list of suggested cipher suites and compression methods. Included in the message is the session id from the previous TLS connection.
Note: This requirement overrides the suggestion in §7.3 UI Requirements, which is safe to do since the combination of the first and second requirements above ensure that mixed content will never load in this page’s context.
An important property in this context is perfect forward secrecy (PFS). Possessing one of the long-term asymmetric secret keys used to establish an HTTPS session should not make it easier to derive the short-term session key to then decrypt the conversation, even at a later time. Diffie–Hellman key exchange (DHE) and Elliptic curve Diffie–Hellman key exchange (ECDHE) are in 2013 the only ones known to have that property. Only 30% of Firefox, Opera, and Chromium Browser sessions use it, and nearly 0% of Apple’s Safari and Microsoft Internet Explorer sessions. Among the larger internet providers, only Google supports PFS since 2011 (State of September 2013).
Jump up ^ Does the browser have mitigations or is not vulnerable for the known attacks. Note actual security depends on other factors such as negotiated cipher, encryption strength etc (see § Cipher table).
A certificate may be revoked before it expires, for example because the secrecy of the private key has been compromised. Newer versions of popular browsers such as Firefox, Opera, and Internet Explorer on Windows Vista implement the Online Certificate Status Protocol (OCSP) to verify that this is not the case. The browser sends the certificate’s serial number to the certificate authority or its delegate via OCSP and the authority responds, telling the browser whether the certificate is still valid.
Be realistic. A lot of admins don’t do that and HTTPS is important for the security and privacy of the user. So it’s the right approach because resources are very often also available via HTTPS even if referenced via HTTP. So good move from Mozilla from the user’s point of view.
What are the policies for deciding trust? It can vary; there’s likely multiple good (and bad) policies. The ideas I’m proposing here are just that: ideas. No doubt this needs a lot of discussion and scrutiny. These are just my jottings to get the pot stirring.
I bought a SSL Certificate from godaddy so I could get the green padlock on my domain. They told me that I have to redirect my site to https://tutorspanish.co.uk/ but when I type this on a browser I get the crossed padlock in read which I know more or less what it means but it does not give much trust to my visitors. They said that my domain needs www in other to get the green padlock. But I do not know how to do it
Even where Diffie–Hellman key exchange is implemented, server-side session management mechanisms can impact forward secrecy. The use of TLS session tickets (a TLS extension) causes the session to be protected by AES128-CBC-SHA256 regardless of any other negotiated TLS parameters, including forward secrecy ciphersuites, and the long-lived TLS session ticket keys defeat the attempt to implement forward secrecy. Stanford University research in 2014 also found that of 473,802 TLS servers surveyed, 82.9% of the servers deploying ephemeral Diffie–Hellman (DHE) key exchange to support forward secrecy were using weak Diffie–Hellman parameters. These weak parameter choices could potentially compromise the effectiveness of the forward secrecy that the servers sought to provide.
Well yes. But this, seemingly simple thing, is fraught with issues. First off all it’s too easy to miss a simple typo. While amaz0n.com might be easy to spot can you honestly say you’d notice if you were on amazn.com? Especially if it had a nice, green, reassuring padlock in the address bar and looked exactly like Amazon.com? It could even just be passing details back and forth to the real Amazon.com so even has all your correct profile details and past history. And that’s before we even getting started on homograph attacks, that use foreign character that look the same as regular ones.
Quick searches can also be performed in some browsers by entering a shortcut and search terms in lieu of a URL. For example, by associating the shortcut “w” with Wikipedia, “w cake” can be entered into the address bar to navigate directly to the Wikipedia article for cake. This feature is available in Firefox, Opera and Google Chrome.
Using this tactic to load 3rd party resources, requires an additional step – contacting the owner of the 3rd party domain and requesting https support. As this solution seems far fetched you may consider using different supplier for the files you were loading from insecure domain(s).
RC4 as a stream cipher is immune to BEAST attack. Therefore, RC4 was widely used as a way to mitigate BEAST attack on the server side. However, in 2013, researchers found more weaknesses in RC4. Thereafter enabling RC4 on server side was no longer recommended.

Because Im not good on the computer, so im not sure when im in a safe site. I want to get a loan, so you have to put in tour personal information and how do you know who you are giving you ss# or driver lic # too ? so I want to be as sure as possible. so your information helped me know this. thanks Approved: 4/3/2012
The term SSL (short for ‘secure socket layer’) describes a technique for encrypting and authenticating data traffic on the internet. With regard to websites, the transfer between the browser and web server is secured. Especially when it comes to e-commerce, where confidential and sensitive information is routinely transferred between different parties, using an SSL certificate or a TLS (‘transport layer security’) is simply unavoidable.
An SSL Certificate is a set of data files that you can add to your server to achieve an encrypted connection between a browser and your server. When installed, a green padlock will be displayed when users visit your site to indicate that the site is secure.
