Descripción

*** Pendiente de traducción *** In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes.<br /> <br /> <br /> <br /> This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historical reasons.<br /> <br /> <br /> <br /> If the password contains characters that cannot be represented in ISO-8859-1, they are silently replaced by `?`. This happens with passwords that contain Chinese, Cyrillic or Greek characters, for example: `αβ123` converts to `??123`.<br /> <br /> <br /> <br /> An attacker can send a request with a digest `Authorization` header crafted with a password made of only `?` characters; the server would match any password of the same length that contains non-ISO-8859-1 characters.<br /> <br /> <br /> <br /> Recent HTTP Digest [RFC-7616](https://datatracker.ietf.org/doc/html/rfc7616) supports a `charset` parameters that defaults to UTF-8 that allows for correct encoding/decoding of passwords.
