Functions

fun String.add0x(): String

Adds 0x prefix to a string if not already present.

fun SecureLocalStorage.deleteAll(keys: List<KeyValueStorageKeys>): List<Pair<KeyValueStorageKeys, SecureLocalStorageResult>>

Delete multiple keys at once. Returns a list of results for each operation.

fun SecureLocalStorage.existAll(keys: List<KeyValueStorageKeys>): Boolean

Check if all specified keys exist.

fun SecureLocalStorage.existAny(keys: List<KeyValueStorageKeys>): Boolean

Check if any of the specified keys exist.

fun SecureLocalStorage.getByteArray(key: KeyValueStorageKeys): ByteArray?

Get a value as ByteArray or null if not found.

fun SecureLocalStorage.getDouble(key: KeyValueStorageKeys): Double?

Get a value as Double or null if not found/invalid.

getDoubleOrDefault

fun SecureLocalStorage.getDoubleOrDefault(key: KeyValueStorageKeys, default: Double): Double

Get a value as Double with a default fallback.

fun SecureLocalStorage.getFloat(key: KeyValueStorageKeys): Float?

Get a value as Float or null if not found/invalid.

getFloatOrDefault

fun SecureLocalStorage.getFloatOrDefault(key: KeyValueStorageKeys, default: Float): Float

Get a value as Float with a default fallback.

fun SecureLocalStorage.getInt(key: KeyValueStorageKeys): Int?

Get a value as Int or null if not found/invalid.

getIntOrDefault

fun SecureLocalStorage.getIntOrDefault(key: KeyValueStorageKeys, default: Int): Int

Get a value as Int with a default fallback.

fun SecureLocalStorage.getString(key: KeyValueStorageKeys): String?

Get a value as String or null if not found/invalid.

getStringOrDefault

fun SecureLocalStorage.getStringOrDefault(key: KeyValueStorageKeys, default: String): String

Get a value as String with a default fallback.

hexToBigInteger

fun String.hexToBigInteger(): BigInteger

Converts a hex string (with or without 0x prefix) to BigInteger.

fun String.hexToByteArray(): ByteArray

Converts a hex string (with or without 0x prefix) to ByteArray.

keccak256Digest

fun ByteArray.keccak256Digest(): ByteArray

Computes the Keccak-256 cryptographic hash of the byte array.

inline fun <R> SecureLocalStorageResult.map(transform: (Any?) -> R): Result<R>

Map success value to another type.

inline fun SecureLocalStorageResult.onFailure(block: (SecureLocalStorageError) -> Unit): SecureLocalStorageResult

Execute a block if the result is a failure.

inline fun SecureLocalStorageResult.onSuccess(block: (Any?) -> Unit): SecureLocalStorageResult

Execute a block if the result is successful.

publicKeyFromBytes

fun ByteArray.publicKeyFromBytes(): ByteArray

Converts a ByteArray into a 32-byte public key representation. If the input ByteArray is longer than 32 bytes, it's truncated. If it's shorter, it's right-aligned within a 32-byte array.

fun SecureLocalStorage.setAll(values: Map<KeyValueStorageKeys, Any>): List<Pair<KeyValueStorageKeys, SecureLocalStorageResult>>

Set multiple values at once. Returns a list of results for each operation.

fun ByteArray.sha256Digest(): ByteArray

Computes the SHA-256 cryptographic hash of the byte array.

fun ByteArray.toBase58BTC(): String

Converts the byte array into a Base58-encoded string following Bitcoin's alphabet.

toBase58CheckEncode

fun ByteArray.toBase58CheckEncode(): String

Encodes the current byte array into a Base58Check-encoded string.

fun BigInteger.toHexString(): String

Converts BigInteger to hex string with 0x prefix.

fun ByteArray.toHexString(): String

Converts a ByteArray to a hex string with 0x prefix.

toPublicKeyToTronAddress

fun ByteArray.toPublicKeyToTronAddress(): String

Converts a ByteArray representing an uncompressed public key into a TRON blockchain address.

toSafeByteArray

fun BigInteger.toSafeByteArray(): ByteArray

Converts BigInteger to byte array, ensuring non-negative representation. Removes the leading zero byte (sign byte) if present.
