• atob

Decode Base64 data.
Parameters:
b64_str: Mandatory, Base64 encoded data
Return:
Decoded data, boolean false on failure (invalid Base64 data)

str = Engine.atob(b64_str)

• btoa

Encode string data to Base64.
Parameters:
str: Mandatory, data to encode
line_len: Optional line length (split encoded data, add end of line after each line_len chars)
add_eol: Optional, add an extra end of line after encoded data
Return:
Base64 encoded data

b64_str = Engine.btoa(str[,line_len[,add_eol]])

• atoh

Decode Base64 data.
Parameters:
b64_str: Mandatory, Base64 encoded data
hex_sep: Optional separator to use between octets. Set it to 'undefined' if not used and hex_upcase is given
hex_upcase: Optional, use upper case characters in hexa
Return:
Hexified string, boolean false on failure (invalid Base64 data)

hex_str = Engine.atoh(b64_str[,hex_sep[,hex_upcase]])

• htoa

Encode hexified binary (string) data to Base64.
Parameters:
hex_str: Mandatory, data to encode
line_len: Optional line length (split encoded data, add end of line after each line_len chars)
add_eol: Optional, add an extra end of line after encoded data
Return:
The string, boolean false on failure (invalid input string).

b64_str = Engine.htob(hex_str[,line_len[,add_eol]])

• btoh

Convert binary (string) data to hexified string.
Parameters:
str: Mandatory, data to hexify
hex_sep: Optional separator to use between octets. Set it to 'undefined' if not used and hex_upcase is given
hex_upcase: Optional, use upper case characters in hexa
Return:
Hexified string

hex_str = Engine.btoh(str[,hex_sep[,hex_upcase]])

• htob

Unhexify binary (string) data.
Parameters:
hex_str: Mandatory, data to unhexify
hex_sep: Optional separator between octets. Set it to 'undefined' if missing or unknown (autodetect)
Return:
The string, boolean false on failure (invalid input string).

str = Engine.htob(hex_str[,hex_sep])

Properties

• DebugFail, DebugTest, DebugGoOn, DebugConf, DebugStub, DebugWarn, DebugMild, DebugCall, DebugNote, DebugInfo, DebugAll

Debug levels to be used when calling Engine.debug() or Engine.alarm().
NOTE:: Debug level is clamped to interval [DebugTest .. DebugAll] unless 'allow_abort' is enabled in javascript.conf (in this case the debug level is clamped to interval [DebugFail .. DebugAll].

• shared

Provides access to Shared object.

• name

Script name. It may not be available.
This is the name assigned to the script.
This property is missing when running javascript eval command.
Example:

javascript.conf:
[scripts]
test=some_script.js

in some_script.js
Engine.name property value is "test"
