JAVA Security - Verify Signature

已关闭 已发布的 4 年前 货到付款
已关闭 货到付款

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.
