13 * We'd like to specially thank the Stud project authors for a very clean
14 * and well documented code which helped us understand how the OpenSSL API
15 * ought to be used in non-blocking mode. This is one difficult part which
16 * is not easy to get from the OpenSSL doc, and reading the Stud code made
17 * it much more obvious than the examples in the OpenSSL package. Keep up
18 * the good works, guys !
19 *
20 * Stud is an extremely efficient and scalable SSL/TLS proxy which combines
21 * particularly well with haproxy. For more info about this project, visit :
22 * https://github.com/bumptech/stud

92 *
93 * Due to API incompatibilities between multiple OpenSSL versions and their
94 * derivatives, it's often tempting to add macros to (re-)define certain
95 * symbols. Please do not do this here, and do it in common/openssl-compat.h
96 * exclusively so that the whole code consistently uses the same macros.
97 *
98 * Whenever possible if a macro is missing in certain versions, it's better
99 * to conditionally define it in openssl-compat.h than using lots of ifdefs.
