The next version of #Fedify will support #LDSignatures (#RsaSignature2017), which means that Fedify will be able to verify activities forwarded by #Mastodon from other servers.
In addition, activities sent with the Context.sendActivity() method will have Linked Data Signatures attached in addition to HTTP Signatures if any RSA-PKCS#1-v1.5 key pairs are present.
We were not motivated by implementing Linked Data Signatures, which is already an outdated standard, but we hope this change will lead to better compatibility and interoperability of Fedify apps!
