| 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 : |

| 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. |
