Hello flichtenheld,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/552?usp=email
to look at the new patch set (#2).
Change subject: Remove redundant call of EVP_CipherInit before EVP_CipherInit_Ex
......................................................................
Remove redundant call of EVP_CipherInit before EVP_CipherInit_Ex
EVP_CipherInit basically is the same EVP_CipherInit_ex except that it
in some instances it resets/inits the ctx parameter first. We already
call EVP_CIPHER_CTX_reset to reset/init the ctx before so this call does
not do anything useful.
OpenSSL 1.0.2:
https://github.com/openssl/openssl/blob/OpenSSL_1_0_2-stable/crypto/evp/evp_enc.c#L94
EVP_CipherInit calls first EVP_CIPHER_CTX_init and then EVP_CipherInit_ex
Our openssl_compat.h has
for these older OpenSSL versions
OpenSSL 3.0:
https://github.com/openssl/openssl/blob/openssl-3.2/crypto/evp/evp_enc.c#L450
basically the same as 1.0.2. Just that method names have been changed.
