Struct ring::error::KeyRejected

pub struct KeyRejected(/* private fields */);

An error parsing or validating a key.

The Display implementation 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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
