migrating existing Destinations from old to new signatures will be added in a
future release. Signature type is encoded in the Destination and Router
Identity, so that new signature algorithms or curves may be added at any time.
The current supported signature types are as follows:
* DSA-SHA1
* ECDSA-SHA256-P256
* ECDSA-SHA384-P384
* ECDSA-SHA512-P521
* EdDSA-SHA512-Ed25519 (as of release 0.9.15)
* RedDSA-SHA512-Ed25519 (as of release 0.9.39)
Additional signature types are used at the application layer only,
primarily for signing and verifying su3 files.
These signature types are as follows:
* RSA-SHA256-2048
* RSA-SHA384-3072
* RSA-SHA512-4096
* EdDSA-SHA512-Ed25519 (as of release 0.9.15)
* EdDSA-SHA512-Ed25519ph (as of release 0.9.25)
