OpenSSL is using regular base64 encoding, see for example https://www.openssl.org/docs/man1.1.1/man3/EVP_EncodeInit.html But if you need base64url encoding, no problem: a simple string replace will help. https://brockallen.com/2014/10/17/base64url-encoding/ Regards, Matthias Von: openssl-users <openssl-users-bounces@xxxxxxxxxxx> Im Auftrag von Benjamin ENTE Gesendet: Freitag, 18.

I'm using OpenSSL 1.0.1e 11 Feb 2013 and I want to know if it's encoding in base64 or in base64url.
