type MD5Password

type MD5Password struct {
	// contains filtered or unexported fields
}

MD5Password implements the PostgresPassword interface for hashing passwords using the PostgreSQL MD5 method

func NewMD5Password

func NewMD5Password(username, password string) *MD5Password

NewMD5Password constructs a new MD5Password struct

func (*MD5Password) Build

func (m *MD5Password) Build() (string, error)

Build creates the MD5 password format for PostgreSQL which resembles "md5" + md5("password" + "username")

type OptionFunc

type OptionFunc func(o *Encryptor)

Option is an application option.

func Algorithm

func Algorithm(algorithm string) OptionFunc

func Iv

func Iv(iv string) OptionFunc

func Key

func Key(key string) OptionFunc

func ReplaceTable

func ReplaceTable(replaceTable string) OptionFunc

func ReplaceWith

func ReplaceWith(replaceWith string) OptionFunc

type SCRAMPassword

type SCRAMPassword struct {
	// Iterations is the number of iterations to run the PBKDF2 algorithm when
	// generating the hashed salted password. This defaults to 4096, which is the
	// PostgreSQL default
	Iterations int
	// SaltLength is the length of the generated salt that is used as part of the
	// PBKDF2 algorithm
	SaltLength int
	// contains filtered or unexported fields
}

SCRAMPassword contains the building blocks to build a PostgreSQL SCRAM verifier. Implements the PostgresPassword interface

func NewSCRAMPassword

func NewSCRAMPassword(password string) *SCRAMPassword

NewSCRAMPassword constructs a new SCRAMPassword struct with sane defaults

func (*SCRAMPassword) Build

func (s *SCRAMPassword) Build() (string, error)

Build creates the SCRAM verifier, which follows the methods defined in the PostgreSQL source, i.e.

https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/include/common/scram-common.h
