  • 9b45b7bba   crypto: rsa - Generate fixed-length output ... Browse Code »

    Every implementation of RSA that we have naturally generates
    output with leading zeroes. The one and only user of RSA,
    pkcs1pad wants to have those leading zeroes in place, in fact
    because they are currently absent it has to write those zeroes
    itself.

    So we shouldn't be stripping leading zeroes in the first place.
    In fact this patch makes rsa-generic produce output with fixed
    length so that pkcs1pad does not need to do any extra work.

    This patch also changes DH to use the new interface.

  • 5a7de9730   crypto: rsa - return raw integers for the ASN.1 parser ... Browse Code »

    Return the raw key with no other processing so that the caller
    can copy it or MPI parse it, etc.

    The scope is to have only one ANS.1 parser for all RSA
    implementations.

    Update the RSA software implementation so that it does
    the MPI conversion on top.

  • 3d5b1ecde   crypto: rsa - RSA padding algorithm ... Browse Code »

    This patch adds PKCS#1 v1.5 standard RSA padding as a separate template.
    This way an RSA cipher with padding can be obtained by instantiating
    "pkcs1pad(rsa)". The reason for adding this is that RSA is almost
    never used without this padding (or OAEP) so it will be needed for
    either certificate work in the kernel or the userspace, and I also hear
    that it is likely implemented by hardware RSA in which case hardware
    implementations of the whole of pkcs1pad(rsa) can be provided.

  • 457e6f73a   crypto: rsa - only require output buffers as big as needed. ... Browse Code »

    rhe RSA operations explicitly left-align the integers being written
    skipping any leading zero bytes, but still require the output buffers to
    include just enough space for the integer + the leading zero bytes.
    Since the size of integer + the leading zero bytes (i.e. the key modulus
    size) can now be obtained more easily through crypto_akcipher_maxsize
    change the operations to only require as big a buffer as actually needed
    if the caller has that information. The semantics for request->dst_len
    don't change.

  • 22287b0b5   crypto: akcipher - Changes to asymmetric key API ... Browse Code »

    Setkey function has been split into set_priv_key and set_pub_key.
    Akcipher requests takes sgl for src and dst instead of void *.
    Users of the API i.e. two existing RSA implementation and
    test mgr code have been updated accordingly.
