CiphergetInstanceRSA

This class implements the RSA algorithm through the Cipher interface. An application can use this class to encrypt or decrypt data with RSA public and ...

In order to create a Cipher object, the application calls the Cipher's getInstance method, and passes the name of the requested transformation to it. ... RSA/ECB/ ...

Cipher cipher = Cipher.getInstance(RSA/ECB/PKCS1Padding);. cipher.init(Cipher.ENCRYPT_MODE, publicKey);. byte[] encryptedBytes = cipher.doFinal(messageToBytes);.

Cipher cipher = Cipher.getInstance(RSA/ECB/OAEPWithSHA-512AndMGF1Padding); ... Cipher cipher = Cipher.getInstance(RSA/ECB/OAEPWithSHA-512AndMGF1Padding);.
