I think you are right. However, it is funny as OpenBSD uses sha256 as
the default auth in ipsec and the header is present:

# grep EVP_sha256 /usr/include/openssl/*
/usr/include/openssl/evp.h:const EVP_MD *EVP_sha256(void);

# strings /usr/lib/libssl.so.11.0 | grep 256
EVP_aes_256_cbc
DH-DSS-AES256-SHA
DH-RSA-AES256-SHA
DHE-DSS-AES256-SHA
DHE-RSA-AES256-SHA
ADH-AES256-SHA
AES-256-CBC
AES(256)
