Hi All,
Is there any way to clone EVP_CIPHER_CTX similar to EVP_MD_CTX_copy is to clone
EVP_MD_CTX object?
My use case:
1. I have many input texts which start with same 1 MB data. They differ
in latter parts.
2. After encrypting first 1 MB data, I want to create a clone of
EVP_CIPHER_CTX and continue executing in different branches.
In some places like
http://www.opensource.apple.com/darwinsource/Current/ruby-22.0.1/ruby/ext/openssl/openssl_missing.c,
I have found EVP_CIPHER_CTX_copy function.
But I want to know why openssl guys did not do this? Is there any problem
associated with this?
Thanks in advance
DP
