not required

Decryption works as expected for any type and size of data. Tested up to file-sizes of 200GB

Fix: Set encoding output for decryption result.

ASCII above 127 are encoded as triplets of values "239,191,189" (=UTF8 65533). From 128+ information is compromised.

Individual decrypted blocks (chunks) are "glued" together.

back in action ... Implementing the decryption routine >1 year after coding the related encryption method. Just to keep myself busy, encryption and decryption is done with different APIs *sarcasm" :D

There are two approaches:

1. Encrypt file and split it into blocks of max size 1MB
2. Split file into blocks of max size 1MB and then encrypt each block

encryption works as expected

1. encoding File/Blob object to ArrayBuffer (needed as input for AES encryption) crashes browser (tested on Chrome) if file is bigger 1GB:
   • check chunking

ToDos

• implement final caseID socketbased
• port encryptData to socketbased
• distinguish between uploading sites (such as CSI, E010, etc.)
• when decrypting, differentiate between files and string
• include IV of encrypted file
• include client PublicKey
• can formData be transported by websockets
  • compile needed socket.emit statement. emit supports Buffer
