Package-level declarations

The utils module is intentionally lightweight. Most cryptographic and encoding operations are handled by the Kotlin Standard Library, TSS Module, and Platform Libraries.

Byte array manipulation
Serialization helpers
Base64 encoding/decoding

This module currently provides minimal utility functions for:

the TSS implementations and wrapper modules. Utility functions for the SilentShard Kotlin Multiplatform library. This module provides common utilities used across

Types

IBufferAsBase64Serializer

object IBufferAsBase64Serializer : KSerializer<ByteArray>

A kotlinx.serialization KSerializer that represents a ByteArray as a Base64 string instead of the default array-of-bytes form.

MessageSigner

interface MessageSigner

Certifies a party's per-session protocol key with a stable identity key.

Functions

decodeBase64

fun String.decodeBase64(): ByteArray

Decodes a standard Base64 string (RFC 4648) back into bytes.

encodeBase64

fun ByteArray.encodeBase64(): String

Encodes the bytes as a standard Base64 string (RFC 4648).

encodeUrlSafeBase64

fun ByteArray.encodeUrlSafeBase64(): String

Encodes the bytes using the URL- and filename-safe Base64 alphabet (RFC 4648 §5).

toHexadecimalString

fun ByteArray.toHexadecimalString(): String

Returns the lowercase hexadecimal representation of the bytes, without separators or prefix.

writeUint16LE

fun ByteArray.writeUint16LE(value: Int, offset: Int)

Writes value as an unsigned 16-bit little-endian integer into this array, occupying offset and offset + 1 (low byte first).
