Create a server supporting encryption/decryption of structured data (JSON, XML) via REST endpoints

[odd]

• Multiple keys/schemes should be supported.
• Annotation marking parts of data to be encrypted should exist for different formats of structured data (JSON, XML).

Example

Input:

{
  "name": "Pelle",
  "password": [["@", "clear", "key-1"], "secret"]
}

Output:

{
  "name": "Pelle",
  "password": [["@", "cipher", "key-1"], "x34dbqwfr"]
}
