Because digital signatures are certificate-based, signers need to obtain a Digital ID before they can apply their signature. This Digital ID can be obtained from one of several cloud signature providers, or by applying the signature using Adobe Acrobat or Acrobat Reader, using a local Digital ID.. The Adobe Sign solution walks the signer through the process: In this web guide, you will learn how to generate ECDSA Signature and verify it using JavaScript. ECDSA stands for Elliptic Curve Digital Signature Algorithm which is widely used for generating digital signatures. Bitcoin, one of the largest digital currency also uses ECDSA for generating digital signatures. Experiment with it. When running code in the Acrobat Javascript console (CTRL-J) you need to put all lines of code on a single line (no line breaks). Then move the cursor to immediately after the last semicolon.

The 'jsrsasign' library provides following features in pure JavaScript. Signature - RSA/RSAPSS/ECDSA/DSA digital signature class wrapper of Java JCE style. MessageDigest - cryptographic hash calculation class wrapper of Java JCE style. MAC - message authentication code hash calculation class wrapper of Java JCE style. ASN.1 encoder/generator. From what I understand, digital signature algorithms are hash-then-sign, and the hash functions used must be cryptographic hashes such as SHA-2 or SHA-3. However, looking up the typical benchmarks of SHA-2 and SHA-3, their speed in terms of throughput (bytes/second) seem to be well under 500MB/s per core on modern laptop CPUs, which is not bad. For web application, to access user's Certificate store (or Digital Signature in USB Token or Smartcard through Certificate store), from modern browsers, which no more supports java applest or activeX, using Browser extension is the solution. One such free browser extension is Signer.Digital. Working can be checked at https://web.signer.digital ...

Next you obviously need the corresponding public key to verify the message.

The GenSig program you are about to create will use the JDK Security API to generate keys and a digital signature for data using the private key and to export the public key and the signature to files. The application gets the data file name from the command line. The following steps create the GenSig sample program.. Prepare Initial Program Structure ... So a javascript solution must exist.
