Digital Signature


A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents.

A valid digital signature, where the prerequisites are satisfied, gives a recipient a very strong reason to believe that the message was created by a known sender (authentication) and that the message was not altered in transit (integrity).

Digital signatures are like electronic “fingerprints.” In the form of a coded message, the digital signature securely associates a signer with a document in a recorded transaction.

Digital signatures use a standard, accepted format, called Public Key Infrastructure (PKI) temuland crypto glossary asymmetric cryptography Asymmetric cryptography is a process that uses a pair of related keys, one public key and one private key, to encrypt and decrypt a message and protect it from unauthorized access or useLearn more, to provide the highest levels of security and universal acceptance.

Everything is a combined signature of other things!
