JAVA Security - Verify Signature

Closed Posted 4 years ago Paid on delivery
Closed Paid on delivery

Working with a client to implement integration between two systems. They are sending me a challenge phrase that has been signed. Need a quick java utility that will verify that the signature for the challenge phrase came from them using an ASCII-armored representation of public key. Prefer implementation using Bouncy Castle but if the validation will work, can use [login to view URL] libs.
