moov-io/cryptfs
Moov's mission is to give developers an easy way to create and integrate bank processing into their own software products. Our open source projects are each focused on solving a single responsibility in financial services and designed around performance, scalability, and ease of use.
cryptfs implements Go's io/fs.FS
interface for interacting with the local filesystem to transparently encrypt/decrypt files. This is useful as a library because it offers applications a well tested routine for keeping data protected.
Project Status
cryptfs is included in multiple open-source projects Moov offers and is used in production environments. Please star the project if you are interested in its progress. If you find any bugs or desire additional encryption/encoding algorithms we would appreciate an issue or pull request. Thanks!
Usage
Cryptfs supports AES and GPG for encryption and Base64 (Standard Raw) encoding. Currently cryptfs is usable as a Go library in your applications. This needs to be initialized prior to reading or writing any files.
AES Cryptor
key := []byte("1234567812345678")) // insecure key
fsys, err := cryptfs.FromCryptor(cryptfs.NewAESCryptor(key))
if err != nil {
// do something
}
fsys.SetCoder(cryptfs.Base64()) // optional, default is the raw bytes
GPG Cryptor
fsys, err := cryptfs.FromCryptor(cryptfs.NewGPGCryptorFile(publicKeyPath, privateKeyPath, password))
if err != nil {
// do something
}
fsys.SetCoder(cryptfs.Base64()) // optional, default is the raw bytes
Once initialized you can perform open/read and write operations.
Open
file, err := fsys.Open(path)
if err != nil {
// do something
}
ReadFile
plaintext, err := fsys.ReadFile(path)
if err != nil {
// do something
}
WriteFile
err := fsys.WriteFile(path, data, 0600)
if err != nil {
// do something
}
Command Line
Moov offers a command line tool for using this library as well. It's handy for operational debugging and testing.
