bitdb attribute encoder & decoder

How it works

1. encode

Encode all BitDB Query attributes to base64

Takes all the h-prefixed and s-prefixed variables in a QUERY and transforms them to base64. Example:

bcode.encode({
  "v": 3,
  "q": {
    "find": {
      "out.b0": {
        "op": 106
      },
      "out.h1": "6d02",
      "out.s2": "Hello World"
    }
  }
})

returns

{
  "v": 3,
  "q": {
    "find": {
      "out.b0": {
        "op": 106
      },
      "out.h1": "bQI=",
      "out.s2": "SGVsbG8gd29ybGQ="
    }
  }
}

2. decode

Find all base64 encoded b-attributes and attach their hex encoded version on the same object

bcode.decode({
  "i": 1,
  "b0": {
    "op": 118
  },
  "b1": {
    "op": 169
  },
  "b2": "C4xgCn8EKdAewSF/r3mR0I3zeG4=",
  "s2": "\u000b�`\n^?\u0004)�\u001e�!^?�y�Ѝ�xn",
  "b3": {
    "op": 136
  },
  "b4": {
    "op": 172
  },
  "str": "<Script: OP_DUP OP_HASH160 20 0x0b8c600a7f0429d01ec1217faf7991d08df3786e OP_EQUALVERIFY OP_CHECKSIG>",
  "e": {
    "v": 50591402,
    "i": 1,
    "a": "qq9cccq20uzzn5q7cyshltmej8ggmumcdc9deqqsa7"
  }
})

returns the following (includes h2):

{
  "i": 1,
  "b0": {
    "op": 118
  },
  "b1": {
    "op": 169
  },
  "b2": "C4xgCn8EKdAewSF/r3mR0I3zeG4=",
  "h2": "0b8c600a7f0429d01ec1217faf7991d08df3786e",
  "s2": "\u000b�`\n^?\u0004)�\u001e�!^?�y�Ѝ�xn",
  "b3": {
    "op": 136
  },
  "b4": {
    "op": 172
  },
  "str": "<Script: OP_DUP OP_HASH160 20 0x0b8c600a7f0429d01ec1217faf7991d08df3786e OP_EQUALVERIFY OP_CHECKSIG>",
  "e": {
    "v": 50591402,
    "i": 1,
    "a": "qq9cccq20uzzn5q7cyshltmej8ggmumcdc9deqqsa7"
  }
