base64 
Lua module for encoding/base64
Usage
Encoding
local base64 = require("base64")
s = base64.RawStdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg
s = base64.StdEncoding:encode_to_string("foo\01bar")
print(s)
Zm9vAWJhcg==
s = base64.RawURLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA
s = base64.URLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==
Decoding
local base64 = require("base64")
s, err = base64.RawStdEncoding:decode_string("Zm9vAWJhcg")
assert(not err, err)
print(s)
foobar
s, err = base64.StdEncoding:decode_string("Zm9vAWJhcg==")
assert(not err, err)
print(s)
foobar
s, err = base64.RawURLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA")
assert(not err, err)
print(s)
this is a <tag> and should be encoded
s, err = base64.URLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==")
assert(not err, err)
print(s)
this is a <tag> and should be encoded

Functions ¶
func CheckBase64Encoding ¶
CheckBase64Encoding checks the argument at position n is a *base64.Encoding
func DecodeString ¶
DecodeString decodes the encoded string with the encoding
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
source := `
local base64 = require("base64")
s, err = base64.RawStdEncoding:decode_string("Zm9vAWJhcg")
assert(not err, err)
print(s)
s, err = base64.StdEncoding:decode_string("Zm9vAWJhcg==")
assert(not err, err)
print(s)
s, err = base64.RawURLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA")
assert(not err, err)
print(s)
s, err = base64.URLEncoding:decode_string("dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==")
assert(not err, err)
print(s)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: foo�bar foo�bar this is a <tag> and should be encoded this is a <tag> and should be encoded
func EncodeToString ¶
EncodeToString decodes the string with the encoding
Example ¶
state := lua.NewState()
defer state.Close()
Preload(state)
source := `
local base64 = require("base64")
s = base64.RawStdEncoding:encode_to_string("foo\01bar")
print(s)
s = base64.StdEncoding:encode_to_string("foo\01bar")
print(s)
s = base64.RawURLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
s = base64.URLEncoding:encode_to_string("this is a <tag> and should be encoded")
print(s)
`
if err := state.DoString(source); err != nil {
log.Fatal(err.Error())
}
Output: Zm9vAWJhcg Zm9vAWJhcg== dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA dGhpcyBpcyBhIDx0YWc-IGFuZCBzaG91bGQgYmUgZW5jb2RlZA==
func LVBase64Encoding ¶
LVBase64Encoding converts encoding to a UserData type for lua
func NewDecoder ¶
func NewEncoder ¶
func NewEncoding ¶
