Package: TYPO3

Subpackage: rsaauth

Versions: 1.2.0 -

Class: tx_rsaauth_loginformhook

Method: getLoginFormTag()

Author: Steffen Gebert

Message: No OpenSSL backend could be obtained for rsaauth.

Description: Login into TYPO3 is not possible anymore, as no OpenSSL backend for rsaauth is available.


  • Activate and configure (on Windows) the PHP module openssl
  • Configure rsaauth to use the openssl executable inside localconf.php
    • Set $TYPO3_CONF_VARS['SYS']['binSetup'] to the executable. E.g. 'openssl=C:/ ... /openssl.exe'
    • If your path to openssl.exe contains blanks, make sure to quote the openssl parameter, e.g. 'openssl="C:/ ... /openssl.exe"'
  • Set $TYPO3_CONF_VARS[TYPO3_mode]['loginSecurityLevel'] to 'normal' instead of 'rsa' (replace TYPO3_mode with BE or FE) and set the hash of your user account's password to the md5 hashed value of your password. This way you can at least access your installation. Please be aware that this is a bad idea and disabling rsaauth/saltedpasswords results in all your passwords being unusable, until openssl is available.

Windows 7 and Xampp

Assuming you installed Xampp into C:\xampp:

  • Activate the PHP module openssl in C:\xampp\php\php.ini. Look for this line:
  • Load fileinfo module as well. Look for this line and uncomment it:
  • Add an environment variable "OPENSSL_CONF" with value C:\xampp\apache\conf\openssl.cnf. Press "Win + PAUSE" to go to the System window. In the left sidebar are the system settings.
  • Either set $TYPO3_CONF_VARS['SYS']['binSetup'] to 'openssl=C:\xampp\apache\bin\openssl.exe' or append C:\xampp\apache\bin to the environment variable PATH (will work for every PHP script not only TYPO3)
    • If your path to openssl.exe contains blanks, make sure to quote the openssl parameter, e.g. 'openssl="C:/ ... /openssl.exe"'
  • Restart Apache
  • If Apache won't start, deactivate the apache ssl module (php has its own) in C:\xampp\apache\conf\httpd.conf like so:
 #LoadModule ssl_module modules/

and near the end of the file:

 #Include conf/extra/httpd-ssl.conf
  • Copy "libeay32.ddl" and "ssleay32.dll" from C:\xampp\php\ to C:\xampp\apache\bin\

Debian Squeeze/Wheezy

Got error after installation of Redmine on Debian (amd64).
Typo3 is version : 6.1.0.
I upgraded to version 6.1.5 trying to solve my pb.

apt-get didn't want to reinstall package openssl (says "unable to find source package").

Solution came when i installed it manually with dpkg -i from :
Which was the version i needed.

Hope it helps.

Alternative solution for error "PHP OpenSSL extension not working: Something went wrong while trying to create a new private key for testing ..." on Debian Wheezy using PHP 5.5 FPM with login spinning forever after updating Typo3 to 6.2.11: Setting 'loginSecurityLevel' => 'normal' in LocalConfiguration helped temporarily for the login issue, but real "solution" was to give everyone read rights on /etc/ssl/openssl.cnf as this seems to be needed by PHP's openssl_pkey_new():
chmod a+r /etc/ssl/openssl.cnf

I got this error when i had the directory /etc/ssl owned by root and no read access for www-data (apache2)
