JavaScript: A very simple way to implement electronic signature

Is there a very simple way in JS to make an electronic signature that can be handled with as much ease as checksums (or hash)?

So if this is the scenario:

------------------------------------       Locked section for client ------------------------------------ | YYYY.MM.DD  ......................| | ........... ......................| | Bla bla bla ......................| | Bla bla bla Bla bla bla..Bla bla .| | Bla bla bla Bla bla bla..Bla bla .| | Bla bla bla Bla bla bla..Bla bla .| | Bla bla bla Bla bla bla..Bla bla .| | Bla bla bla ......................| | Bla bla bla ......................| ------------------------------------ |    HASH: HA2S2EM3CA12EDIAJED      | ------------------------------------ "Open" comment textfield for clients ------------------------------------ | HE34ADOV2DSASA452123 ...(signer A)| | GHEAVOED12dHSAV2123J ...(signer B)| 

HE34ADOV2DSASA452123 is generated by a private key owned by the signer.

Then the decryption (with some sort of public key) of HE34ADOV2DSASA452123 would give something like YYYY.MM.DD Bla bla bla or return the hash (HA2S2EM3CA12EDIAJED) of the section.

Likewise the decryption of GHEAVOED12dHSAV2123J would give something like YYYY.MM.DD Bla bla bla or return the hash (HA2S2EM3CA12EDIAJED) of the section.

Note there is no requirement for this to be secured against evil master minds, just against "layman" fraud...

Try node module XML Advanced Electronic Signatures.

It uses Web Crypto for cryptographic operations. Hence it can be used both in browsers and in Node.js.
