Mobile Encryption Accelerator

This accelerator provides functionalities for RSA encryption and decryption. It allows you to encrypt data using either a public key provided by the Identity Realm or a public key provided by any other means, and decrypt data encrypted with the corresponding private key.

Features

• Generate RSA key pairs
• Encrypt data using a public key
• Decrypt data using a private key
• Supports different key sizes (512, 1024, 2048, 3072, 4096 bits)
• Allows specifying a custom cipher type

Constructors

• BBRSACryptor(keySize: KeySize): Creates a new instance with a randomly generated key pair of the specified size.
• BBRSACryptor(publicKey: String, privateKey: String): Creates a new instance with the provided public and private keys (Base64 encoded).
• BBRSACryptor(keySize: KeySize, cipherType: String): Creates a new instance with a randomly generated key pair of the specified size and cipher type.
• BBRSACryptor(publicKey: String, privateKey: String, cipherType: String): Creates a new instance with the provided public and private keys (Base64 encoded) and cipher type.

Methods

• getPublicKey(): Returns the public key as a Base64 encoded string.
• getPrivateKey(): Returns the private key as a Base64 encoded string.
• encrypt(message: String): Encrypts the given message using the public key.
• encrypt(message: String, publicKey: String): Encrypts the given message using the provided public key (Base64 encoded).
• decrypt(encryptedMessage: String): Decrypts the given encrypted message using the private key.
• decrypt(encryptedMessage: String, privateKey: String): Decrypts the given encrypted message using the provided private key (Base64 encoded).

Example Usage

// Generate a new key pair with a key size of 2048 bits
val cryptor = BBRSACryptor.create(BBRSACryptor.KeySize.BIT_2048)

// Get the public and private keys
val publicKey = cryptor.getPublicKey()
val privateKey = cryptor.getPrivateKey()

// Encrypt a message using the public key
val message = "This is a secret message"
val encryptedMessage = cryptor.encrypt(message)

// Decrypt the encrypted message using the private key
val decryptedMessage = cryptor.decrypt(encryptedMessage)

println(decryptedMessage) // Output: This is a secret message

Important Notes

• Ensure that the provided public and private keys are valid and compatible with each other.
• Choose an appropriate key size based on your security requirements.
• This library uses Base64 encoding for public and private keys.
