Subject: [PATCH 1/2] rsa: Fix build with OpenSSL 1.1.x
|
|
|
|
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.
