* Naming
* If this is not some OpenPGP standard I follow rule that `DES` should be
upper case as it is abreviation and `Triple` should be camel-case as it
is normal word hence `TripleDES`
* rename `errors2` -> `errorsPGP`
* long lines
* https://github.com/golang/go/wiki/CodeReviewComments#line-length
* I bit improved long lines based on my folding
* reuse type in definition if possible i.e. `a string, b string, c string` -> `a,b,c string`
* `if long_statetent(); err!=nil {` -> `long_statement;↵ if err!=nil {`
* spaces around operators (e.g. `a + b` -> `a+b`)
* removing empty lines on start and end of scope
* comments
* on all exported functions
* start with function name
* import:
* order in alphabet
* separate native, golang.org/x/ and our libs
