Fred Montier Posted May 29, 2022 Share Posted May 29, 2022 HI Folks Encrypt a message securely with AES+QR e.g Crypto paper wallet (Ethereum private keys, Bitcoin) https://codepen.io/mallendeo/pen/brZJBa This is not my project and I haven't made any changes to it. But it's so good and so well done that I couldn't pass it up without publicizing the project of this excellent programmer and his original idea. It allows you to generate a QRCode with an encrypted text in it and with a password, allowing its eventual decoding. Simple and practical and with a JS code without an additional gram of fat. The JavaScript code, shows how to implement encryption, trigger the device's camera to decrypt, generate a QrCode and trigger the print dialog with everything assembled in an elegant and well done way without VCL Report Components,etc. Is a nice repository to every day's problems. Keep because you will need it. Share and see the author's repository in codepen (See the source code in HTML and JavaScript). It's the kind of project you might need to keep some secrets that really stay safe. Enjoy PS: See our new Component Package Code Injector at https://www.unigui.com.br/uniGUICodeInjector-eng.html And our printer server solution for uniGUI - lite version (component package to print PDF, Direct Printing to POS etc) https://www.unigui.com.br/uniGUIPRINTERServer-Lite-eng.html The final solution to direct print to POS printers --- PT-BR Este não é um projeto meu e nem fiz nenhuma modificação nele. Mas é tão bom e tão bem feito que não poderia deixar passar sem divulgar o projeto deste excelete programador e sua ideia original. Ele permite que você gere um QrCode com um texto encriptado nele e com uma senha, permitindo sua eventual decodificação. Simples e prático e com um código JS sem uma grama adicional de gordura. O código JavaScript, mostra como implementar encriptação, acionar a camera do dispositivo para desencriptar, gerar um QrCode e disparar o dialog de impressão com tudo montado de forma elegante e bem feita. Compartilhem e veja o repositorio do autor no codepen (Veja no código fonte em HTML e JavaSCript). É o tipo de projeto que você pode precisar para guardar alguns segredos que realmente ficam seguros. Project available only in the pack Silver at https://unigui.express 1 Link to comment Share on other sites More sharing options...

Regards Well, if you can print directly to your local POS printer (or any) without browser printer dialog, using uniGUI or any web app, kudos to you ! It's not a problem with printer but how browsers works and security issues. Can't access directly i/o devices like printer, disk, usb ports, etc...with out a dialog or browser intervention. If you have a biz CRM printing receipts (for instance) without any handles like that... nice. There are lots of people you could put out of biz with your solution. No one can, at the moment. Soon, Chrome , if Apple ever Apply. 1 Link to comment Share on other sites More sharing options...
