The
crypto.createVerify() method is used to create a
Verify object that uses the stated algorithm. Moreover, you can use
crypto.getHashes() to access the names of all the available signing algorithms.
Syntax:
crypto.createVerify( algorithm, options )
Parameters: This method accept two parameters as mentioned above and described below:
- algorithm: It is a string type value. A Sign instance can be created by applying the name of a signature algorithms, like 'RSA-SHA256', in place of a digest algorithms.
- options: It is an optional parameter that is used to control stream behavior. It returns an object.
Return Value: It returns
Verify object.
