Tools for testing TLS/SSL configurations and HTTP security features.

Cross-platform PowerShell script that tests TLS versions, HTTP versions, compression, QUIC, and HSTS using a self-contained cURL binary.

Requirements: PowerShell 7.5+

.\TLS-checker.ps1 -Domain "example.com" -TestType All
.\TLS-checker.ps1 -Domain "example.com" -TestType TLS -Quiet

Really strong TLS/SSL scanner. This one is included as a submodule from a project that I like. It scans ciphers, protocols, certificates, and vulnerabilities.

Currently, the Git submodule is pinned at a specific version. If missing after cloning, run:

git submodule update --init

Requirements: Bash 3.2+, OpenSSL

./testssl.sh/testssl.sh example.com
./testssl.sh/testssl.sh --vulnerable example.com
