#Key Import

Import cryptographic key pairs based on supported algorithm using the walt.id crypto lib.

#Importing Public Key

If you have an existing public key (in raw format), you can import it with the importRawPublicKey method reference below:

import id.walt.crypto.keys.KeyType
import id.walt.crypto.keys.jwk.JWKKey
import id.walt.crypto.keys.jwk.JWKKeyMetadata

suspend fun main() {
    val rawPublicKey: ByteArray = // Your raw public key here
    val importedKey = JWKKey.importRawPublicKey( KeyType.RSA, rawPublicKey, JWKKeyMetadata(2048) )
    println( "Imported Key ID: " + importedKey.getKeyId() )
}

#Importing Keys From JWK and PEM

Similarly, you can import keys from JWK and PEM format using the importJWK(jwk: String) and importPEM(pem: String) methods respectively.

import id.walt.crypto.keys.JWKKey

suspend fun main() {
val jwk: String = // Your JWK string here
val pem: String = // Your PEM string here

    val importedJWK = JWKKey.importJWK( jwk )
    val importedPEM = JWKKey.importPEM( pem )

    println( "JWK Key ID: " + importedJWK.getOrThrow().getKeyId() )
    println( "PEM Key ID: " + importedPEM.getOrThrow().getKeyId() )

}
