Decrypt Method

Decrypts data using a key.

Syntax

azurekeys.decrypt(keyName, algorithm, [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 the given Algorithm. The VersionId configuration setting can be used to target a specific key version.

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.

The key specified by KeyName must be an RSA key; EC keys cannot be used for encryption/decryption.

The Algorithm parameter specifies which algorithm to use to decrypt the data; it must match the algorithm used to encrypt the data previously. Possible values are:

Algorithm Description
RSA1_5 RSAES-PKCS1-v1_5
RSA-OAEP RSAES OAEP using SHA-1 and MGF1 with SHA-1
RSA-OAEP-256 RSAES OAEP using SHA-256 and MGF1 with SHA-256
