badssl.com VS RegExr

Probably to demo it? I wish Google had "this link will always be considered harmful", like the stuff on https://badssl.com/.

With SSLVersionMin, I think TLS 1.0 and TLS 1.1 protocols are already disabled (they were originally going to be disabled in 2020, but it was postponed). If I try going to test pages on https://badssl.com/ that use those protocols, Brave displays an "Unsupported protocol" error page with error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH – with no option for the user to bypass the error page. However, I'm not sure why InTune won't allow you to configure it to TLS 1.2 minimum version anyway.

See https://badssl.com/, or for a simple example of what happen when you access a page redirected by naughty DNS, set your private DNS to family.adguard-dns.com, then try opening PornHub.

.DESCRIPTION This cmdlet tests a URI for connectivity, and checks whether the TLS certificate is valid, expired, expiring soon, and returns information about the certificate when used with InformationLevel 'Detailed'. .PARAMETER Uri Specifies an HTTP/HTTPS URI. For example, https://www.powershellgallery.com .PARAMETER InformationLevel Specifies whether to return detailed information, or a simple $true or $false. .EXAMPLE Test-Uri https://badssl.com/ Returns a detailed TestUriResult with an IsTrusted property value of $true under normal circumstances. .EXAMPLE Test-Uri https://badssl.com/ -InformationLevel Quiet Returns a value of $true under normal circumstances. .EXAMPLE Test-Uri https://expired.badssl.com/ Returns a detailed TestUriResult with an IsExpired property value of $true .EXAMPLE Test-Uri https://expired.badssl.com/ Returns a detailed TestUriResult with an IsExpired property value of $true .EXAMPLE Test-Uri https://tls-v1-1.badssl.com:1011/ -SslProtocol Tls11 Returns a detailed TestUriResult where IsTrusted and UriTestSucceeded are $true, because we've specified to use SslProtocol Tls11. .EXAMPLE Test-Uri https://tls-v1-1.badssl.com:1011/ Returns a detailed TestUriResult where IsTrusted and UriTestSucceeded are $false, because only Tls12 and Tls13 are trusted by default. #> [CmdletBinding()] param ( [Parameter(Mandatory, ValueFromPipeline, ValueFromPipelineByPropertyName, Position = 0)] [uri[]] $Uri, [Parameter()] [System.Security.Authentication.SslProtocols[]] $SslProtocol = @([System.Security.Authentication.SslProtocols]::Tls12, [System.Security.Authentication.SslProtocols]::Tls13), [Parameter()] [ValidateSet('Detailed', 'Quiet')] [string] $InformationLevel = 'Detailed' ) process { [System.Security.Authentication.SslProtocols]$trustedProtocols = 0 $SslProtocol | Foreach-Object { $trustedProtocols = $trustedProtocols -bor $_ } foreach ($address in $Uri) { $result = [pscustomobject]@{ PSTypeName = 'TestUriResult' Uri = $address RemoteAddress = $null RemotePort = $null SourceAddress = $null RemoteCertificate = $null CipherAlgorithm = $null HashAlgorithm = $null SslProtocol = $null TcpTestSucceeded = $false UriTestSucceeded = $false IsExpired = $false IsExpiring = $false IsTrusted = $false } try { $tcpClient = [net.sockets.tcpclient]::new($address.Host, $address.Port) $result.TcpTestSucceeded = $true $result.RemoteAddress = $tcpClient.Client.RemoteEndPoint.Address $result.RemotePort = $tcpClient.Client.RemoteEndPoint.Port $result.SourceAddress = $tcpclient.Client.LocalEndPoint.Address if ($address.Scheme -eq 'https') { $stream = $tcpClient.GetStream() $sslStream = [net.security.sslstream]::new($stream, $false, { $true }) $protocols = 0; [enum]::GetValues([System.Security.Authentication.SslProtocols]) | Where-Object { $_ -match '(Ssl|Tls)' } | Foreach-Object { $protocols = $protocols -bor $_ } $sslStream.AuthenticateAsClient($address.Host, $null, $protocols, $true) $certInfo = [security.cryptography.x509certificates.x509certificate2]::new($sslStream.RemoteCertificate) $result.SslProtocol = $sslStream.SslProtocol $result.RemoteCertificate = $certInfo $result.CipherAlgorithm = $sslStream.CipherAlgorithm $result.HashAlgorithm = $sslStream.HashAlgorithm $result.IsExpired = $certInfo.NotAfter -le (Get-Date) $result.IsExpiring = $certInfo.NotAfter -le (Get-Date).AddDays(30) $result.IsTrusted = $certInfo.Verify() -and ($sslStream.SslProtocol -band $trustedProtocols) $result.UriTestSucceeded = $result.IsTrusted -and !$result.IsExpired -and ($sslStream.SslProtocol -band $trustedProtocols) if (-not ($sslStream.SslProtocol -band $trustedProtocols)) { Write-Warning "The transport layer security protocol $($sslStream.SslProtocol) is not in the list of trusted protocols: $trustedProtocols." } if ($result.IsExpired) { Write-Warning "Certificate for '$address' is expired.

Just use https://badssl.com/ to test the various errors.

For developers needing to test responses to various SSL issues there is https://badssl.com. Not my site, but one I use frequently to demonstrate the result of bad/incorrectly configured certificates.

https://badssl.com/ is a nice website, it shows all the ways ssl can be misconfigured. So you can see how it affects connections.

Modern Web Browsers implement robust, thorough control over SSL/TLS connections, including trust list management, protocol downgrade protection, etc. Using an HTTPS interception proxy therefore means the proxy has to implement all those controls, properly. At the very least, this shouldn't have any problems connecting to https://badssl.com/ (Google's test site, although I don't think this is currently maintained).

When thinking about how I might compare an arrangement to the contiguous group of damaged springs, I used regexr.com to experiment with very specific regexs that used the numbers.

There are plenty of online regex tools to test and experiment with regex patterns. Some popular ones include RegExr, RegEx101, and RegexPlanet.

Using regexr.com it at least appears to work as expected.

If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.

First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:

Regexr has been an invaluable tool as a beginner.

RegExr simplifies working with regular expressions. This online tool provides a visual interface for building and testing regex patterns in real-time, making regex less intimidating.

Ho did you arrive at the regex? I usually use a website to , such as https://regex101.com/, https://regexr.com/, https://regex-generator.olafneumann.org/ in combination of each other, as some explain better than the other.

I pulled this into regexr.com and it yielded the same results except it removed :41:
