Have supplied with the help of a radio button. As the encryptionĬan be done using both the keys, you need to tell the tool about the key type that you RSA Encryptionįor encryption and decryption, enter the plain text and supply the key.

Hence, it is recommended to use 2048-bit keys. There's a significant increase in CPU usage as a result of a 4096 bit key size. A 4096 bit key size does provide a reasonable increase in strength over a 2048 bit key size but the encryption strength doesn't drop off after 2048 bits. Since 2015, NIST recommends a minimum of 2048-bit keys for RSA. To generate the keys, select the RSA key size among 515, 1024, 20 bit and then click on the button to generate the keys for you. The private key is used to generate digital signatures,Īnd the public key is used to verify the digital signatures. The public key pem can easily be transferred over the network.In the first section of this tool, you can generate public and private keys. Public static KeyPair generateRsaKeyPair(int keySize) throws Exception ) Encrypting content in javascript and decrypting in java.

android encrypting the content using a public key generated on javascript and then javascript decrypting it. I also needed to support the whole process in reverse i.e. Android should then be able to successfully decrypt the data using its private key.

The idea was to pick up a public key generated on android and use it to encrypt content in javascript. The library also supported decryption using a private key using RSAES-OAEP/SHA-256/MGF1-SHA-256 which is compatible with Java’s RSA/ECB/OAEPWithSHA-256AndMGF1Padding algorithm. It also had a fair performance according to this evaluation. While developing an initial pairing mechanism for Ambient Dynamix, I had already settled on the forge library for javascript because of the availability of symmetric, asymmetric encryption algorithms, password based key derivation functions and hashing algorithms. It’s extremely painful to implement RSA Encryption so that data encrypted on either of these platforms can be easily decrypted on the other platforms and even more so for someone like me who had almost zero knowledge of programming using encryption algorithms.
