+## Генерация **jwtRS256** ключа
+
+```sh
+ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key  # Don't add passphrase
+openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
+```
+
+Команды ниже конвертируют ключи в однострочник
+
+```sh
+awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}'  jwtRS256.key
+awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}'  jwtRS256.key.pub
+```
