Types

type EncryptedField

type EncryptedField struct {
	Cipher cipher.Block
}

EncryptedField handles encrypted and decryption of values to and from database columns.

func (*EncryptedField) PostRead

func (e *EncryptedField) PostRead(fieldAddr interface{}, scanTarget interface{}) error

PostRead is called after a Scan operation. It is given the value returned by PreRead and a pointer to the raw struct field. It is expected to fill in the struct field if the two are different.

func (*EncryptedField) PreRead

func (e *EncryptedField) PreRead(fieldAddr interface{}) (scanTarget interface{}, err error)

PreRead is called before a Scan operation. It is given a pointer to the raw struct field, and returns the value that will be given to the database driver.

func (*EncryptedField) PreWrite

func (e *EncryptedField) PreWrite(field interface{}) (saveValue interface{}, err error)

PreWrite is called before an Insert or Update operation. It is given a pointer to the raw struct field, and returns the value that will be given to the database driver.
