Description

This function accepts a plain text and hashed value and compares the text with the hashed value.

Syntax

VerifySCryptHash(plaintext, hashedString, options)

History

ColdFusion (2021 release): Added this function.

Parameters

Parameter Description
plaintext
(Required) The input string on which the hash function must be run.
hashedString (Required) The hashed output from the GenerateSCryptHash function.
options

(Optional) A struct with the following values:

  • keyLength - key length for the algorithm (as defined in scrypt this is dkLen). The default is currently 32.

Example

<cfscript>
    stringToEncrypt="Sample string"
    options = StructNew() 
    options.cpucost = 1024 
    options.memorycost = 64 
    options.keylength = 16 
    options.saltlength = 8
    sCrypted=GenerateSCryptHash(stringToEncrypt,options) 
    // struct
    decryptOptions = structNew()
    decryptOptions.keylength=16
    backToString = VerifySCryptHash(stringToEncrypt, sCrypted, decryptOptions)
    writeDump(backToString) 
</cfscript>

Output

YES
