Decrypt Method

Decrypts data using a key.

Syntax

googlekms.decrypt(keyName, versionId, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method decrypts data using the key specified by KeyName and (for asymmetric keys) VersionId.

The data to decrypt is taken from the the specified InputFile or the InputData property. The decrypted data is output to the the specified OutputFile or the OutputData property.

For symmetric keys, VersionId must be empty; the server automatically detects which version of the symmetric key to use for decryption.

For asymmetric keys, VersionId must be specified.
