Android Question Encrypted file & FirebaseStorage

[npsonic]

I want to upload huge files >100Mb with FirebaseStorage lib, but I would also want to encrypt the file before uploading it.

I could encrypt file before uploading it, but there might not be enough memory available for the bigger encrypted files.

Is there any way to do this without creating another encrypted file locally before uploading?
Can I somehow use CipherOutputStream and CipherInputStream for this?

Encrypting / decrypting such large files will be slow. You will need to create a temporary file with B4XEncryption or Encryption libraries.

Is there anyway to do it without creating temporary file?

Could I somehow read the file piece by piece and encrypt the pieces before uploading?
I could download and decrypt the pieces before merging pieces into one file.

Yes, you will need to encrypt a chunk each time. However you will also need to write the encrypted chunk to a temporary file.
