Groovy Encode / Decode

Recently, I needed to encode and decode some information for a project I was working on. I wrote a quick little snippet to show encoding and decoding a string in the same program.

CODE:


def me = "Jim Shingler"
println "Me: ${me}"

// Encode it
def encoded = me.bytes.encodeBase64()
println "encoded: ${encoded}"

// because I need a string for decoding
StringWriter sw = new StringWriter()
encoded.writeTo(sw)

// Decode it
String decoded = new String(sw.toString().decodeBase64())
assert decoded == me
println "decoded: ${decoded}"


OUTPUT:


Me: Jim Shingler
encoded: SmltIFNoaW5nbGVy
decoded: Jim Shingler
