The problem is that you are returning the toString() of the call to Base64.encodeBase64(bytes) which returns a byte array. So what you get in the end is the default string representation of a byte array, which corresponds to the output you get. Instead, you should do: encodedfile = new String(Base64.encodeBase64(bytes), “UTF-8”);
You can use magic numbers to detect a MIME type (check here the list of file signatures). However, file signatures are not 100% reliable and you can easily encounter false positives. Of course, there are tasks when a such solution is more than enough. So if you have a Base64 string and want to identify … Read more
I was originally using some VBScript code from Antonin Foller: Base64 Encode VBS Function and Base64 Decode VBS Function. Searching Antonin’s site, I saw he had some code for quoted printable encoding, using the CDO.Message object, so I tried that. Finally, I ported the code mentioned in Mark’s answer to VBScript (also used some code … Read more
Swift import Foundation extension String { func fromBase64() -> String? { guard let data = Data(base64Encoded: self) else { return nil } return String(data: data, encoding: .utf8) } func toBase64() -> String { return Data(self.utf8).base64EncodedString() } }
What you’ve provided is perfectly functional. It will produce a base64-encoded string of the bytes of your source string encoded in UTF-16. If you’re asking if UTF-16 can represent any character in your string, then yes. The only difference between UTF-16 and UTF-32 is that UTF-16 is a variable-length encoding; it uses two-bytes to represent … Read more
Base64 needs a string with length multiple of 4. If the string is short, it is padded with 1 to 3 =. import base64 code = “YWRtaW46MjAyY2I5NjJhYzU5MDc1Yjk2NGIwNzE1MmQyMzRiNzA=” base64.b64decode(code) # b’admin:202cb962ac59075b964b07152d234b70′
Instead of encodestring consider using b64encode. Later does not add \n characters. e.g. In [11]: auth = b’username@domain.com:passWORD’ In [12]: base64.encodestring(auth) Out[12]: b’dXNlcm5hbWVAZG9tYWluLmNvbTpwYXNzV09SRA==\n’ In [13]: base64.b64encode(auth) Out[13]: b’dXNlcm5hbWVAZG9tYWluLmNvbTpwYXNzV09SRA==’ It produces identical encoded string except the \n
You can use the MSXML Base64 encoding functionality as described at www.nonhostile.com/howto-encode-decode-base64-vb6.asp: Function EncodeBase64(text As String) As String Dim arrData() As Byte arrData = StrConv(text, vbFromUnicode) Dim objXML As MSXML2.DOMDocument Dim objNode As MSXML2.IXMLDOMElement Set objXML = New MSXML2.DOMDocument Set objNode = objXML.createElement(“b64”) objNode.dataType = “bin.base64” objNode.nodeTypedValue = arrData EncodeBase64 = Replace(objNode.Text, vbLf, “”) Set … Read more
The preferred way to do this in groovy is: def encoded = “Hello World”.bytes.encodeBase64().toString() assert encoded == “SGVsbG8gV29ybGQ=” def decoded = new String(“SGVsbG8gV29ybGQ=”.decodeBase64()) assert decoded == “Hello World”
