We shall move to use 2048 bit keysize for generated RSA certificates in our examples in our WildFly documentation to avoid a warning that is generated by keytool distributed by JDKs in version 11+:

$ keytool -genkeypair -alias client -keyalg RSA -keysize 1024 -validity 365 -keystore client.keystore.jks -dname "CN=client" -keypass secret -storepass secret

Warning:
The generated certificate uses a 1024-bit RSA key which is considered a security risk and is disabled.

This change affects following two chapters in our WildFly documentation currently:

• https://docs.wildfly.org/24/WildFly_Elytron_Security.html#configure-ssltls
• https://docs.wildfly.org/24/WildFly_Elytron_Security.html#Web_Single_Sign_On
