object ChaCha20Encryptor

CryptoServiceInfo

data class CryptoServiceInfo(val name: String, val lookup: String, val algorithm: String, val providerName: String, val providerVersion: String)

Which security provider serves one cryptographic lookup, read off the instance the platform returned.

EncryptedData

class EncryptedData(val data: ByteArray) : ByteDataContainer

PlainData

class PlainData(val data: ByteArray) : ByteDataContainer

SHA256Key

class SHA256Key(val data: ByteArray) : ByteDataContainer

Functions

assetCryptoServices

internal fun assetCryptoServices(): List<CryptoServiceInfo>

Which providers serve asset crypto, for the security providers debug screen.

internal fun assetCryptoServices(): List<CryptoServiceInfo>

Which providers serve asset crypto, for the security providers debug screen.

calcFileMd5

fun calcFileMd5(dataSource: <Error class: unknown class>): String?

Method used to calculate the digested MD5 hash of a relatively small byte array

calcFileSHA256

fun calcFileSHA256(dataSource: <Error class: unknown class>): ByteArray?

Method used to calculate the digested SHA256 hash of a relatively small byte array

calcMd5

fun calcMd5(bytes: ByteArray): String

cryptoServiceInfo

fun cryptoServiceInfo(name: String, lookup: String, resolve: () -> <Error class: unknown class><String, Provider>): CryptoServiceInfo?

Performs resolve and reads the algorithm and provider off the instance it returned, so what is reported is what the platform actually handed back.
