deleteKey

abstract suspend fun deleteKey(address: String): Result<Unit>
Deletes the signing key for the given wallet address.

​
deletePendingKey

abstract suspend fun deletePendingKey(publicKeyBase64: String): Result<Unit>
Deletes a pending key that was never mapped to a wallet address.

​
generateKey

abstract suspend fun generateKey(address: String?): Result<String>
Generates a new P-256 signing key and stores it.

​
getKey

abstract suspend fun getKey(address: String): String?
Returns the base64-encoded uncompressed public key for the given wallet address, or null if not found.

getSecurityLevel

abstract suspend fun getSecurityLevel(address: String): String?
Returns a human-readable string describing the security level of the key for the given wallet address (e.g. “StrongBox”, “TEE”, “Software”), or null if the key is not found.

​
hasKey

abstract suspend fun hasKey(publicKeyBase64: String): Boolean

​
isAvailable

abstract suspend fun isAvailable(): Boolean
Returns true if this storage backend is available on the current device/platform.

​
mapAddressToKey

abstract suspend fun mapAddressToKey(address: String, publicKeyBase64: String): Result<Unit>
Associates a previously generated pending key with a wallet address.

​
signHexMessage

abstract suspend fun signHexMessage(address: String, hexMessage: String): Result<Pair<String, String>>
Signs a hex-encoded message using the key for the given wallet address.

​
signHexMessageWithPendingKey

abstract suspend fun signHexMessageWithPendingKey(publicKeyBase64: String, hexMessage: String): Result<Pair<String, String>>
Signs a hex-encoded message using a pending key (not yet mapped to a wallet address).

​
signMessage

abstract suspend fun signMessage(address: String, message: String): Result<Pair<String, String>>
Signs a base64-encoded message using the key for the given wallet address.
