BE_SignatureVerifyRSA

BE_SignatureVerifyRSA ( data ; publicKey ; signature {; algorithm } )

 

Verifies if signature is valid for data by comparing the message digest of data with the digest obtained from signature by decrypting it using publicKey.

 

Version 4.0 : Added.

 

Parameters :

  • data : The source data that was signed. It can be text or container field.
  • publicKey : The public key (as text) to verify the digital signature. PKCS#1 and PKCS#8 PEM formats are supported.
  • signature : The digital signature. It can be container field or Base64 encoded text.
  • algorithm ( optional ) : The hash algorithm (as text) to calculate the digest of the data. "SHA256" will be used when it's empty or omitted.
 

 

Result : 1 if the signature is verified successfully. 0 otherwise.
