Any of those help Use quoted-printable encoding. Any language should support that. http://en.wikipedia.org/wiki/Quoted-printable

What text encoding scheme do you use when you have binary data that you need to send over an ascii channel?

hop of those help? For encoding cookie values, you need to be careful. See this older answer:

I wish this help you I think you are giving "maps" (KV pairs) too much value. As you've pointed out, JSON has a small number of types: numbers, strings, true and false, null, arrays, and objects. You can think of objects and "maps" as being the same thing. Objects can be built up of the other types, for example:
code :
{
    "person": {
        "name": "John"
    }
}
{
    "mimetype" : "application/octet-stream”,
    "metadata" : [ ],
    "value" :   "TWFuIGlzIGRpc3Rpbmd1aXNoZWQsIG5vdCBvbmx5IGJ5IGhpcyByZWFzb24sIGJ1dCBieSB0aGlzIHNpbmd1bGFyIHBhc3Npb24gZnJvbSBvdGhlciBhbmltYWxzLCB3aGljaCBpcyBhIGx1c3Qgb2YgdGhlIG1pbmQsIHRoYXQgYnkgYSBwZXJzZXZlcmFuY2Ugb2YgZGVsaWdodCBpbiB0aGUgY29udGludWVkIGFuZCBpbmRlZmF0aWdhYmxlIGdlbmVyYXRpb24gb2Yga25vd2xlZGdlLCBleGNlZWRzIHRoZSBzaG9ydCB2ZWhlbWVuY2Ugb2YgYW55IGNhcm5hbCBwbGVhc3VyZS4=",
}
var obj = JSON.parse(json);
var value = obj.value; // This is a string

wish help you to fix your issue encoding/binary.Write uses reflection, so it will be slower than anything that manually constructs the buffer. Below is an example of such a function:
code :
import (
    "encoding/binary"
)

func (p *packet) ToBytes() []byte {
    buff := make([]byte, 2 + 8 + 3 + len(p.blob))

    binary.BigEndian.PutUint16(buff[:2], p.dataLength)
    copy(buff[2:10], p.id[:])
    buff[10] = p.pairity
    buff[11] = p.shards
    buff[12] = p.flags
    copy(buff[13:], p.blob)

    return buff
}

this will help The docs confirm that your approach is ok.
base64.b64encode(byte_obj).decode('utf-8') is correct - base64.b64encode requires bytes as input:

I wish this help you This really depends on the nature of the binary data, and the constraints that "text" places on your output.
First off, if your binary data is not compressed, try compressing before encoding. We can then assume that the distribution of 1/0 or individual bytes is more or less random.
