goal is to provide an implementation that is feature complete +compared to the GPG backend but doesn't require any external binaries, +especially no GPG. Of course this would break compatilibity to existing +GPG deployments and users of different pass implementations, but +especially for closed teams with no existing GPG deployment this should +make little to no difference. + +Motivation +---------- + +While GPG is believed to be very secure and it supports a wide range of +applications and devices, it's not really user friendly. Even passioned +[crypto experts](https://moxie.org/blog/gpg-and-me/) don't enjoy working with GPG and for +newcomers it's a major hurdle. For the gopass developers it's about the +most time consuming task to provide support and implement workaround for +GPG issues. This doesn't mean that GPG is bad, but security is hard and +complex and GPG adds a lot of flexiblity on top of that so the result +is complex and complicated. + +WARNING +------- + +We are no crypto experts. While this code uses professional implementations of +well known and rather easy to use crypto primitives there is still a lot of room +for making mistakes. This code so far has recieved no kind of security audit. +Please don't use it for anything critical unless you have reviewed and verified +it yourself and are willing to take any risk. + +Status

It works in concert with the Go source code generated +for .proto files by the protocol compiler. + +A summary of the properties of the protocol buffer interface +for a protocol buffer variable v: + + - Names are turned from camel_case to CamelCase for export. + - There are no methods on v to set fields; just treat + them as structure fields. + - There are getters that return a field's value if set, + and return the field's default value if unset. + The getters work even if the receiver is a nil message. + - The zero value for a struct is its correct initialization state. + All desired fields must be set before marshaling. + - A Reset() method will restore a protobuf struct to its zero state. + - Non-repeated fields are pointers to the values; nil means unset. + That is, optional or required field int32 f becomes F *int32. + - Repeated fields are slices. + - Helper functions are available to aid the setting of fields. + msg.Foo = proto.String("hello") // set field + - Constants are defined to hold the default values of all fields that + have them. They have the form Default_StructName_FieldName. + Because the getter methods handle defaulted values, + direct use of these constants should be rare. + - Enums are given type names and maps from names to values. + Enum values are prefixed by the enclosing message's name, or by the + enum's type name if it is a top-level enum. Enum types have a String + method, and a Enum method to assist in message construction. + - Nested messages, groups and enums have type names prefixed with the name of + the surrounding message type. + - Extensions are given descriptor names that start with E_, + followed by an underscore-delimited list of the nested messages + that contain it (if any) followed by the CamelCased name of the + extension field itself. HasExtension, ClearExtension, GetExtension + and SetExtension are functions for manipulating extensions. + - Oneof field sets are given a single field in their message, + with distinguished wrapper types for each possible field value. + - Marshal and Unmarshal are functions to encode and decode the wire format. + +When the .proto file specifies `syntax="proto3"`, there are some differences: + + - Non-repeated fields of non-message type are values instead of pointers. + - Enum types do not get an Enum method. + +The simplest way to describe this is to see an example. +Given file test.proto, containing + + package example;
