a key.</p> |
| <p>The <code>Display</code> implementation and <code><KeyRejected as Error>::description()</code> |
| 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.</p> |
| <p>Here is an incomplete list of reasons a key may be unsupported:</p> |
| <ul> |
| <li> |
| <p>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.</p> |
| </li> |
| <li> |
| <p>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.</p> |
| </li> |
| <li> |
| <p>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.</p> |
| </li> |
| <li> |
| <p>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.</p> |
| </li> |
| <li> |
| <p>Wrong algorithm: The key is not valid for the algorithm in which it was |
| being used.</p> |
| </li> |
| <li> |
| <p>Unexpected errors: Report this as a bug.</p> |
| </li> |
| </ul> |
