Remove SHA-1 thumbprint usage

[javierdlg]

• Renames --sha1 argument to a more generic -cfp/--certificate-fingerprint argument to allow the use of various RSA algorithms when searching for a matching certificate.
• Adds a new CLI argument -cfpa/--certificate-fingerprint-algorithm which allows specifying the certificate fingerprint algorithm used to find a matching certificate within the provided CSP
• Adds new tests for -cfpa
• Removes support for insecure algorithms (SHA 1 to 128)
