# Electronic and Digital Signatures

Two ways to sign: simple intent-based methods or cryptographically secure signatures.

### Electronic Signature

A **basic digital signing method**, examples include:

* Typing your name in a signature box
* Pasting an image of your signature
* Clicking a “Sign” button

Electronic signatures show intent but usually lack strong identity verification.

### Digital Signature

A **secure form of e-signature** using cryptographic technology and PKI.

Key points:

* Issued by licensed Certificate Authorities (CAs)
* Linked to a unique Digital Signature Certificate (DSC)
* Provides encryption, authentication, and tamper-evidence
* Becomes invalid if the document is altered after signing

**Note:** Both types can be legally valid, but digital signatures are required for sensitive/regulated documents.
