Parameters:

session - The SessionContext for invoking this command - may be null if not invoked within a session context (e.g., offline tool or session unknown).

keyType - The reported / encode key type

keyData - The key data bytes stream positioned after the key type decoding and making sure it is one of the supported types

headers - Any headers that may have been available when data was read

Returns:

The decoded PublicKey

Throws:

java.io.IOException - If failed to read from the data stream

java.security.GeneralSecurityException - If failed to generate the key
