==Full Title or Meme==
A [[Digital Signature]] is a string of bits created by a cryptographic process that is extremely difficult to create without access to a [[Private Key Component|Private Key]].

==Context==
* Nearly all of our digital lives depends on the ability to make a mark that can be known to have been make by the [[Subject]].
* A (sem-)legal definition is a mark or sign made by an individual on an instrument or document to signify knowledge, approval, acceptance, or obligation.<ref>The Free Dictionary by Farlex https://legal-dictionary.thefreedictionary.com/signature</ref><blockquote>The term signature is generally understood to mean the signing of a written document with one's own hand. However, it is not critical that a signature actually be written by hand for it to be legally valid. It may, for example, be typewritten, engraved, or stamped. The purpose of a signature is to authenticate a writing, or provide notice of its source, and to bind the individual signing the writing by the provisions contained in the document.<blockquote></blockquote>Because a signature can obligate a party to terms of a contract or verify that the person intended to make a last will and testament, the law has developed rules that govern what constitutes a legally valid signature. The Internet and other forms of telecommunication have created the need to transact legally binding agreements electronically. Almost all states have passed laws that recognize the validity of [[Digital Signature]]s."</blockquote>

==Problems==
* Not all [[Subject]]s are legal entities, so the meaning of the signature would be unclear.
* [[Private Key Component|Public/Private Key]] technology is itself subject to attack and so the meaning of a security public key technology is subject to revision from time to time as technology advances.
