* Initialized basic outline of TOTP backend using Postgresql backend as template
* Updated TOTP backend.go's structure and help string
* Updated TOTP path_roles.go's structure and help strings
* Updated TOTP path_role_create.go's structure and help strings
* Fixed typo in path_roles.go
* Fixed errors in path_role_create.go and path_roles.go
* Added TOTP secret backend information to cli commands
* Fixed build errors in path_roles.go and path_role_create.go
* Changed field values of period and digits from uint to int, added uint conversion of period when generating passwords
* Initialized TOTP test file based on structure of postgresql test file
* Added enforcement of input values
* Added otp library to vendor folder
* Added test steps and cleaned up errors
* Modified read credential test step, not working yet
* Use of vendored package not allowed - Test error
* Removed vendor files for TOTP library
* Revert "Removed vendor files for TOTP library"
This reverts commit fcd030994b.
* Hopefully fixed vendor folder issue with TOTP Library
* Added additional tests for TOTP backend
* Cleaned up comments in TOTP backend_test.go
* Added default values of period, algorithm and digits to field schema
* Changed account_name and issuer fields to optional
* Removed MD5 as a hash algorithm option
* Implemented requested pull request changes
* Added ability to validate TOTP codes
* Added ability to have a key generated
* Added skew, qr size and key size parameters
* Reset vendor.json prior to merge
* Readded otp and barcode libraries to vendor.json
* Modified help strings for path_role_create.go
* Fixed test issue in testAccStepReadRole
* Cleaned up error formatting, variable names and path names. Also added some additional documentation
* Moveed barcode and url output to key creation function and did some additional cleanup based on requested changes
* Added ability to pass in TOTP urls
* Added additional tests for TOTP server functions
* Removed unused QRSize, URL and Generate members of keyEntry struct
* Removed unnecessary urlstring variable from pathKeyCreate
* Added website documentation for TOTP secret backend
* Added errors if generate is true and url or key is passed, removed logger from backend, and revised parameter documentation.
* Updated website documentation and added QR example
* Added exported variable and ability to disable QR generation, cleaned up error reporting, changed default skew value, updated documentation and added additional tests
* Updated API documentation to inlude to exported variable and qr size option
* Cleaned up return statements in path_code, added error handling while validating codes and clarified documentation for generate parameters in path_keys
