Warning
From version 27 (77), spSize is kept for backward compatibility. This property is replaced by spLength.
The spLength property is used to:
  • Get the hash output length. This property can be used for items of type "Password" defined in the data model editor or programmatically.
  • Set the hash output length (only for "Password" items defined programmatically).
Example
// Describe the AFile file
...
 
// Describe the "Password" item
MyItem is Item Description
MyItem.Name = "Password"
MyItem.Type = hItemSecurePassword
MyItem.spDerivation = SP_PBKDF2
MyItem.spHash = SP_SHA2_256
MyItem.spIterationCount = 20000
MyItem.spLength = 256
 
// Validate the description of the "Password" item
HDescribeItem(AFile, MyItem)
 
// Validate the description of AFile file
...
