> As part of HDDS-2174 we are deleting GDPR Encryption Key on delete file
> operation.
> However, if KMS is enabled, we are skipping GDPR Encryption Key approach when
> writing file in a GDPR enforced Bucket.
> {code:java}
> final FileEncryptionInfo feInfo = keyOutputStream.getFileEncryptionInfo();
> if (feInfo != null) {
> KeyProvider.KeyVersion decrypted = getDEK(feInfo);
> final CryptoOutputStream cryptoOut =
> new CryptoOutputStream(keyOutputStream,
> OzoneKMSUtil.getCryptoCodec(conf, feInfo),
> decrypted.getMaterial(), feInfo.getIV());
> return new OzoneOutputStream(cryptoOut);
> } else {
> try{
> GDPRSymmetricKey gk;
> Map<String, String> openKeyMetadata =
> openKey.getKeyInfo().getMetadata();
> if(Boolean.valueOf(openKeyMetadata.get(OzoneConsts.GDPR_FLAG))){
> gk = new GDPRSymmetricKey(
> openKeyMetadata.get(OzoneConsts.GDPR_SECRET),
> openKeyMetadata.get(OzoneConsts.GDPR_ALGORITHM)
> );
> gk.getCipher().init(Cipher.ENCRYPT_MODE, gk.getSecretKey());
> return new OzoneOutputStream(
> new CipherOutputStream(keyOutputStream, gk.getCipher()));
> }
> }catch (Exception ex){
> throw new IOException(ex);
> }
> {code}
> In such scenario, when KMS is enabled & GDPR enforced on a bucket, if user
> deletes a file, we should delete the {{FileEncryptionInfo}} from KeyInfo,
> before moving it to deletedTable, else we cannot guarantee Right to Erasure.
