sslsniff is designed to create man-in-the-middle (MITM) attacks for SSL/TLS connections, and dynamically generates certs for the domains that are being accessed on the fly. The new certificates are constructed in a certificate chain that is signed by any certificate that is provided. sslsniff also supports other attacks like null-prefix or OCSP attacks to achieve silent interceptions of connections when possible.
