Encode/decode SMTP AUTH username/passwords

By admin on March 20, 2009 in Uncategorized

When using SMTP AUTH, the username and password are base64 encoded. Here’s a snip of perl that will encode a string:

perl -MMIME::Base64 -e 'print encode_base64("username");'

1	perl -MMIME::Base64 -e 'print encode_base64("username");'

This will produce something like this:

dXNlcm5hbWU=

1	dXNlcm5hbWU=

And here’s the decode:

perl -MMIME::Base64 -e 'print decode_base64("dXNlcm5hbWU=");'

1	perl -MMIME::Base64 -e 'print decode_base64("dXNlcm5hbWU=");'

which of course yields:

username
