The Beginning
A Sumerian clay tablet, dating
back to around 3100 BC, has the
markings of the scribe Gar Ama,

examples of the use of words
and symbols to denote identity.

![Earliest know signature - El Cid - History of Sign](http://wsign.cloud/wp-content/plugins/revslider/public/assets/assets/dummy.png)
The earliest known signature from a well-known historical figure belongs to the nobleman and military leader "El Cid" of medieval Spain.
This concept of signature is important,
because it lays the foundations for what we call a documented expression of trust.
A document with a signature is to be trusted to express the will or the consent of the person that has signed this document.

Digital
1976 | 1977
Whitfield Diffie and Martin Hellman, in 1976 first described the idea of a digital signature scheme, but they only theorized the existence of such schemes.
In 1977, Ronald Rivest, Adi Shamir and Len Adleman invented the RSA algorithm, which could be used to produce a sort of primitive digital signature.

A new PDF
1999 | 2008
In 1999 the possibility of embedding digital signatures on documents is added to PDF format files.
In 2008 the PDF format becomes an open standard within the "International Organization for Standardization" (ISO) and termed as ISO 32000, the standard contains the digital signature as part of the format.
