Result: Convert the SHA-256 Hash to Base64 Format

Step 1: Convert to Base64

To convert the hash to Base64 form, use an online tool like Base64 Encode:

Example of Base64 conversion

After conversion, you'll receive a final Base64 string like this:

iIx/AtYu7TpAu5cma4JdDXio5bayFSi89axnyOCjfFo=

Alternative approach using a command-line

This command removes colons from a SHA-256 string, then converts the hexadecimal output to a Base64-encoded binary string for Talsec's configuration.

echo "88:8C:7F:02:D6:2E:ED:3A:53:BB:9C:A6:6B:82:5C:0D:78:A8:E5:B6:B2:11:28:BC:F5:AC:67:C8:E0:A3:7C:5A" | tr -d ':' | xxd -r -p | base64

This command will output the final Base64 string:

iIx/AtYu7TpAu5cma4JdDXio5bayFSi89axnyOCjfFo=

Step 2: Use resulting string in your Talsec configuration ✅

Your work here is done. Insert it into your Talsec configuration.
