The client doesn't work with custom credentials

[fredrikaubert]

When creating a AmazonSQSSecureClient with a custom aws credentials you get an exception when trying to send a message:
com.amazonaws.services.kms.model.AWSKMSException: The security token included in the request is invalid (Service: AWSKMS; Status Code: 400; Error Code: UnrecognizedClientException;

Relevant stacktrace snippet:
at no.cantara.aws.sqs.KMSCryptoUtil.generateDataKey(KMSCryptoUtil.java:118) at no.cantara.aws.sqs.KMSCryptoUtil.encrypt(KMSCryptoUtil.java:106) at no.cantara.aws.sqs.AmazonSQSSecureClient.deflate(AmazonSQSSecureClient.java:212) at no.cantara.aws.sqs.AmazonSQSSecureClient.sendMessage(AmazonSQSSecureClient.java:152)

It seems to be caused by the getAWSKMS-method in KMSCryptoUtil where DefaultAWSCredentialsProviderChain is hardcoded:

private static AWSKMS getAWSKMS(final Region region) {
        if (!REGION.containsKey(region)) {
            AWSKMSClient client = new AWSKMSClient(new DefaultAWSCredentialsProviderChain());
            client.setRegion(region);
            REGION.put(region, client);
        }
        return REGION.get(region);
    }

The the client is created this way(Kotlin):

val credentials = BasicAWSCredentials(accessKey, secretKey )
val credentialsProvider = AWSStaticCredentialsProvider(credentials)
val sqsClient = AmazonSQSSecureClient.create(credentialsProvider, region, kmsCmkId, s3Bucket );

When providing the same credentials as environment variables everything works as expected.
