ssh_SSLeay_add_all_algorithms()

[Robert Dugal]

Please disregard my earlier post. I believe I have figured out the answer myself.

It looks like beginning with 5.7p1 calls to SSLeay_add_all_algorithms() were replaced with OpenSSL_add_all_algorithms().
In OpenSSL 1.0.0d the include file evp.h then redefines OpenSSL_add_all_algorithms() to either OPENSSL_add_all_algorithms_conf() or OPENSSL_add_all_algorithms_noconf() depending on whether OPENSSL_LOAD_CONF is defined. It also defines SSLeay_add_all_algorithms() as OpenSSL_add_all_algorithms().
OPENSSL_add_all_algorithms_conf() is basically equivalent to ssh_SSLeay_add_all_algorithms().

So ssh_SSLeay_add_all_algorithms() isn't needed with OpenSSL 1.0.0d and probably for several other versions of openssl.

I am confused on how ssh_SSLeay_add_all_algorithms() get used in the ssh applications for openssh-5.7p1 and later releases.
I don't see any of the applications making calls to ssh_SSLeay_add_all_algorithms().
There is a macro that redefines SSLeay_add_all_algorithms() to ssh_SSLeay_add_all_algorithms() but I don't see any code calling SSLeay_add_all_algorithms().


In openssh-5.6p1 and earlier releases (I looked as far back as openssh-4.7p1) all these sources below have calls to SSLeay_add_all_algorithms(), 
which means that when configured --with-ssl-engine would get replaced as ssh_SSLeay_add_all_algorithms():
ssh-add.c 
ssh-agent.c
ssh-keygen.c
ssh-keysign.c
ssh.c
sshd.c

But starting with openssh-5.7p1 these calls are all gone.
Is this a bug or can anyone explain how this should work in 5.6p1 and later?   

SSLeay_add_all_algorithms() is replaced with OpenSSL_add_all_algorithms().
