Can anyone recommend a straightforward way/tool to convert hex to base64?
I'm using Linux and OS X.

Use xxd
with the -r
argument (and possibly the -p
argument) to convert from hex to plain binary/octets and base64 to convert the binary/octet form to base64.
For a file:
cat file.dat | xxd -r -p | base64
For a string of hex numbers:
echo "6F0AD0BFEE7D4B478AFED096E03CD80A" | xxd -r -p | base64

Well, it depends on the exact formatting of your data. But you can do it with a simple shell scripts:
echo "obase=10; ibase=16; `cat in.dat`" | bc | base64 > out.dat
Modify as needed depending on your data.
3That will convert the string of decimal digits. It's not clear if this is what the OP wants or if he has hex digits and wants the bytes they represent converted to base64. – Paused until further notice. – 2010-06-29T14:21:39.303

Well, if your hex data is the hex view of a file, just attach the file to a outlook or thunderbird message and then save the message to somewhere. Then open the file with a text editor and see B64 code :)
It functions on Windows, but I think it is a universal way since saving as .EML the attachment is encoded to B64.
You want to convert Hex or Binary to Base64? Scriptable or is this a one-shot deal? – Chris S – 2010-06-29T14:17:20.983
