io.jsonwebtoken.security.SignatureException: Unavailable RSA Signature algorithm 'RSASSA-PSS'

[Elshad1]

Hello!
I am trying to create a JWT but I am getting this error message

io.jsonwebtoken.security.SignatureException: Unavailable RSA Signature algorithm 'RSASSA-PSS'.
    at io.jsonwebtoken.impl.crypto.SignatureProvider.createSignatureInstance(SignatureProvider.java:68)
    at io.jsonwebtoken.impl.crypto.RsaProvider.createSignatureInstance(RsaProvider.java:69)
    at io.jsonwebtoken.impl.crypto.RsaSigner.doSign(RsaSigner.java:53)
    at io.jsonwebtoken.impl.crypto.RsaSigner.sign(RsaSigner.java:43)
    at io.jsonwebtoken.impl.crypto.DefaultJwtSigner.sign(DefaultJwtSigner.java:59)
    at io.jsonwebtoken.impl.DefaultJwtBuilder.compact(DefaultJwtBuilder.java:353)

Mу code:

private fun generateJwt(): String {
    var privateKeyPem: PemObject? = null
    PemReader(InputStreamReader(context.assets.open("private.pem"))).use { reader ->
        privateKeyPem = reader.readPemObject()
    }

    val keyFactory = KeyFactory.getInstance("RSA")
    val privateKey = keyFactory.generatePrivate(PKCS8EncodedKeySpec(privateKeyPem?.content))

    val now = Instant.now()

    return Jwts.builder()
        .setHeaderParam("kid", KEY_ID)
        .setIssuer(SERVICE_ACCOUNT_ID)
        .setAudience(AUDIENCE)
        .setIssuedAt(Date.from(now))
        .setExpiration(Date.from(now.plusSeconds(360)))
        .signWith(privateKey, SignatureAlgorithm.PS256)
        .compact()
}

My dependencies:

api 'io.jsonwebtoken:jjwt-api:0.11.2'
runtimeOnly 'io.jsonwebtoken:jjwt-impl:0.11.2'
runtimeOnly('io.jsonwebtoken:jjwt-orgjson:0.11.2') {
    exclude group: 'org.json', module: 'json' //provided by Android natively
}
api 'org.bouncycastle:bcprov-jdk15on:1.60'

Do you have a sample project that we can run? What JDK were you using for this test?
