    en.wikipedia.org/wiki/List_of_file_signatures

    A file signature is data used to identify or verify the content of a file. Such signatures are also known as magic numbers or magic bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.

  3. Code signing - Wikipedia

    en.wikipedia.org/wiki/Code_signing

    Many code signing systems will store the public key inside the signature. Some software frameworks and OSs that check the code's signature before executing will allow you to choose to trust that developer from that point on after the first run. An application developer can provide a similar system by including the public keys with the installer.

    the signature verifying algorithm that uses the public key, message and digital signature to confirm the authenticity of the message. For PDF documents, the signature data is incorporated directly within the signed PDF document, much as an ink signature becomes an integral part of a paper document, allowing the complete self-contained PDF file ...

    In cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm that was described by Claus Schnorr.It is a digital signature scheme known for its simplicity, among the first whose security is based on the intractability of certain discrete logarithm problems.

    en.wikipedia.org/wiki/Magic_number_(programming)

    The programmer might infer the meaning after reading the code carefully, but it is not obvious. [6] Magic numbers become particularly confusing when the same number is used for different purposes in one section of code. It is easier to alter the value of the number, as it is not duplicated.

  9. Digital signature - Wikipedia

    en.wikipedia.org/wiki/Digital_signature

    Alice signs a message—"Hello Bob!"—by appending a signature which is computed from the message and her private key. Bob receives both the message and signature. He uses Alice's public key to verify the authenticity of the signed message. A digital signature is a mathematical scheme for verifying the authenticity of digital messages or ...
