Outdated module in new Linux distros

This module is totally outdated in any Linux distro that had removed OpenSSL 1 support (for example Debian 12). It is not recommended to use OpenSSL anymore as it is not secure anymore since previous year

When you try to compile the module it will show this error and it cannot be compiled:

encrypted-session-nginx-module/src/ngx_http_encrypted_session_cipher.c:90:5: error: ‘MD5’ is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]

Start with encrypted-session-nginx-module/src/ngx_http_encrypted_session_cipher.c, especially the MD5 calls reported at lines 90 and 228. Reproduce the module compilation on Debian 12 or another Linux distribution using OpenSSL 3, then trace the affected encryption and decryption paths. Done means the module compiles without the reported deprecated-declarations errors and the existing behavior remains covered.
