Struct ring::error::KeyRejected [−][src]
An error parsing or validating a key.
The Display
implementation and <KeyRejected as Error>::description()
will return a string that will help you better understand why a key was
rejected change which errors are reported in which situations while
minimizing the likelihood that any applications will be broken.
Here is an incomplete list of reasons a key may be unsupported:
-
Invalid or Inconsistent Components: A component of the key has an invalid value, or the mathematical relationship between two (or more) components required for a valid key does not hold.
-
The encoding of the key is invalid. Perhaps the key isn’t in the correct format; e.g. it may be Base64 (“PEM”) encoded, in which case the Base64 encoding needs to be undone first.
-
The encoding includes a versioning mechanism and that mechanism indicates that the key is encoded in a version of the encoding that isn’t supported. This might happen for multi-prime RSA keys (keys with more than two private prime factors), which aren’t supported, for example.
-
Too small or too Large: One of the primary components of the key is too small or two large. Too-small keys are rejected for security reasons. Some unnecessarily large keys are rejected for performance reasons.
-
Wrong algorithm: The key is not valid for the algorithm in which it was being used.
-
Unexpected errors: Report this as a bug.
