Android Question Certificate X509 - PKCS#1 v1.5

[BluSky76]

I have to encrypt the string using a certificate (.cer) but despite the various tips on the forum I get errors.

Can you give us a hand?

Thanks

Have you seen this tutorial: https://www.b4x.com/android/forum/threads/using-rsa-in-b4a-to-communicate-with-php-openssl.59445/ ?

You need to extract the public key from the certificate. Can you post the .cert file? I will take a look at the weekend.
