Adds the following API functions:
- API to get signature key IDs for mobile:
func (msg *PGPMessage) GetHexSignatureKeyIDsJson() []byte
- API to get encryption key IDs for mobile:
func (msg *PGPMessage) GetHexEncryptionKeyIDsJson() []byte
- API to get the number of key packets in a PGP message:
func (msg *PGPSplitMessage) GetNumberOfKeyPackets() (int, error)
- API in package `helper` to encrypt a PGP message to an additional key:
func EncryptPGPMessageToAdditionalKey(messageToModify *crypto.PGPSplitMessage, keyRing *crypto.KeyRing, additionalKey *crypto.KeyRing) error
Using the notation data packets of signatures, we add a way to
set a context to detached signatures.
We also add a way to enforce that signatures have the right context
during verification.
* Update header version to 2.0.0
* Add space to cleartext message armouring
* Fix password encrypted binary files
* Clear key private params in helpers
* Do not unlock key if private key is nil
* Document changes
* Use defer for ClearPrivateKeyParams
* Refactor library, remove duplicates
* Rebuild structure to use Messages and Signature models
* Use PGPSplitMessage
* Remove signature model
* Various fixes
* Add helpers with tests
* Fixes, add some docs, add tests
* Add attachment helpers
* Add helpers Symmetric encryption
* Edit docs + examples
* Rename kr to keyRing
* Various fixes for documentation
* Edit JSON handling functions, add decrypt keyring via token
* Add proposal changes doc
* Fix CI
* Drop *Message functions, join CleartextMessage and BinaryMessage
* Change canonicalization and trimming only to text signatures
* Add cleartextsignature, detach signature from message model, move helpers
* Documentation, remove optional parameters
* Move verification to separate model
* Don't return message in VerifyDetached
* Update table of contents in readme
* Appease golint
* Run go fmt
* Rename Encrypt/DecryptMessageWithPassword to ..WithToken
These functions shouldn't be used with user-provided passwords,
as they don't do any key-stretching.
* Change key generation usernames
* 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
