The rsa_st struct has been made opaque in 1.1.x, add forward compatible code to access the n, e, d members of rsa_struct.
EVP_MD_CTX_cleanup has been removed in 1.1.x and EVP_MD_CTX_reset should be called to reinitialise an already created structure. --- lib/rsa/rsa-sign.c | 44 ++++++++++++++++++++++++++++++++++++++------ 1 file changed, 38 insertions(+), 6 deletions(-)
