How to disambiguate signer types in operation json

Question

The set_options operation JSON returned by Horizon does not disambiguate between signer_keys of different types (hash, signed txn hash, account).

// sha256 hash
"signer_key": "XCVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKVKV6IF",

//  Ed25519 public key
"signer_key": "GAQUWIRXODT4OE3YE6L4NF3AYSR5ACEHPINM5S3J2F4XKH7FRZD4NDW2",

// Pre-authorized txn hash
"signer_key": "TCPY4QKJLOI6XLFFU7EN6FO7Y5PEFWBP6V4SXXXSQMRW2OYE27KGH4ZP",

We know that any value that doesn't start with G cannot be a public key. But can we infer anything else?

XDR deserialisation disambiguates this enumeration. Can the JSON API do the same?

Answer 1

At the moment the JSON API does not disambiguate like SDR deserialization does. Hopefully, the JSON API will be able to disambiguate different signature types in the future.
