Cryptography

The Cryptography class provides methods for encryption, decryption, signing, and verification of data using various cryptographic algorithms.

Examples

const cryptography = new Cryptography({
		keys: ['key1', 'key2', 'key3'],
		encryptKey: '',
		encryptKeySingle: '',
})

const encryptedData = cryptography.encrypt('Hello, World!')
const decryptedData = cryptography.decrypt(encryptedData)

const signature = cryptography.signature()
const isVerified = cryptography.signatureVerify(signature)

// creates a KrugerGold Token Address
const address = cryptography.address()

const encodedData = cryptography.base64Encode('Hello, World!')
const decodedData = cryptography.base64Decode(encodedData)
const isEncodedOrNot = cryptography.isBase64Encoded(encodedData)
