    Cascading AES-256-CTR->AES-256-CTR

    Posted: 02 Jan 2019 12:54 PM PST

    Assuming independent keys and authentication are used, is there anything inherently dangerous with cascading the same algorithm together? Is there anything about using independent algorithms inherently safer? (Camellia-OFB->AES-CTR for example)

    Other thoughts why one example would be preferred over the other?

    Where can I find test vectors for rfc8018 (PBKDF2 with different hash functions)?

    Every rfc document usually has a test vector somewhere, there is rfc6070 which only has test vectors for rfc2898 (PBKDF2 only with SHA1 and MD2&5) but I am looking for more like tests for SHA224, 256, 384, 512,...

    I look after a network for a small accountancy practise. The backup disk filled full up.

    They got CrySIS / Dharma encryption on their Win10 box connected to the internet.

    Retrospect is 20:20.

    I'm screwed.

    They don't answer their email?
