The default key algorithm for the `keytool -genkeypair` and `keytool -genseckey` commands has been removed. You must now specify the key algorithm by including the `-keyalg` option when using the `-genkeypair` or `-genseckey` commands. If the `-keyalg` option is not specified, the `keytool` will terminate with the error message: "The -keyalg option must be specified".
