Descriptions

In the Bouncy Castle JCE Provider version 1.55 and earlier the other party DH public key is not fully validated. This can cause issues as invalid keys can be used to reveal details about the other party's private key where static Diffie-Hellman is in use. As of release 1.56 the key parameters are checked on agreement calculation.

En Bouncy Castle JCE Provider, en versiones 1.55 y anteriores, no se valida completamente la clave pública DH de la otra parte. Esto puede causar problemas, ya que las claves inválidas pueden emplearse para revelar detalles sobre la clave privada de la otra parte donde se emplea Diffie-Hellman estático. En la versión 1.56, los parámetros clave se comprueban sobre un cálculo de acuerdo.
