hexlify and unhexlify

[Jonas Galvez]

Is there any built-in module that does this for me?

def hexlify(msg)
msg.split("").collect { |c| c[0].to_s(16) }.join
end
def unhexlify(msg)
msg.scan(/../).collect { |c| c.to_i(16).chr }.join
end

puts hexlify("In Ruby...")
puts unhexlify("496e20527562792e2e2e")
