It seems that some code changes are required: > For at least some ECIES variants (e.g. when using CBC) there is an issue with potential malleability of a nonce (implying silent malleability of the plaintext) that must be sent alongside the ciphertext but is outside the IES integrity check. For this reason the automatic generation of nonces with IED is now disabled and they have to be passed in using an IESParameterSpec. The current advice is to agree on a nonce between parties and then rely on the use of the ephemeral key component to allow the nonce (rather the so called nonce) usage to be extended. https://www.bouncycastle.org/releasenotes.html , changes in 1.72 -- This is an automated message from the Apache Git Service.
