WebThe digital signature is sent along with the original file for its verification by the receiver. Digital Signature Verification: Sender computes the cryptographic hash of the received file or message by using the same hashing algorithm. Sender decrypts the digital signature by using the public key of the sender to get the hash sent by the sender. WebOct 5, 2016 · The test vectors linked below can be used to informally verify the correctness of digital signature algorithm implementations (in FIPS 186-2 and FIPS 186-4) using the validation systems listed above. Response files (.rsp): the test vectors are properly formatted in response (.rsp) files. Vendor response files must match this format exactly.
