Takes a public key in SubjectPublicKeyInfo PEM form and runs the pinned OpenSSL
Takes a public key in SubjectPublicKeyInfo PEM form and runs the pinned OpenSSL build's own consistency checks over it, then reports the algorithm, the key size in bits and the parameters it found. This catches keys that parse but are structurally unusable: a modulus that is not a valid product, curve parameters that do not match a known group, a size that no longer meets the build's security level. The reported bit count comes from the key itself, not from the label a producer attached.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
