func (*SecureData) Decrypt ¶

func (s *SecureData) Decrypt(data []byte, passphrase string) ([]byte, error)

Decrypt decrypt the data. The data should be stored with a 32 byte salt which is append at the end of the data

func (*SecureData) DecryptFile ¶

func (s *SecureData) DecryptFile(filename string, passphrase string) ([]byte, error)

func (*SecureData) DecryptHex ¶

func (s *SecureData) DecryptHex(data string, passphrase string) (string, error)

func (*SecureData) DecryptString ¶

func (s *SecureData) DecryptString(data string, passphrase string) (string, error)

func (*SecureData) DeriveKey ¶

func (s *SecureData) DeriveKey(password, salt []byte) ([]byte, []byte, error)

DeriveKey creates a secure key from a given password. It also accepts a salt which is used to increase the security of the key to prevent Rainbow tables attacks. If the salt is nil, then a secure salt will be generated using scrypt.

func (*SecureData) Encrypt ¶

func (s *SecureData) Encrypt(data []byte, passphrase string) ([]byte, error)

Encrypt encrypts the data with a passphrase. Salt is used on the passphrase and stored in the last 32 bytes of the data (appended decrypted) Example: asdfadsfasdfasdfasdf<salt>

func (*SecureData) EncryptFile ¶

func (s *SecureData) EncryptFile(filename string, data []byte, passphrase string)

func (*SecureData) EncryptString ¶

func (s *SecureData) EncryptString(data string, passphrase string) (string, error)

EncryptString encryptes a string to a hex encoded string using a passphrase and salt. A prefix is also added to it (if defined)

func (*SecureData) FromHex ¶

func (s *SecureData) FromHex(data []byte) ([]byte, error)

func (*SecureData) FromHexString ¶

func (s *SecureData) FromHexString(data string) ([]byte, error)

func (*SecureData) IsEncrypted ¶

func (s *SecureData) IsEncrypted(data string) int

IsEncrypted returns if the given data is encrypted or not. The data is encrypted if it starts with the encryption marker. If an empty string is used as the encryption prefix, then the it can not be reliably checked if the data is enrypted or not. 1 - data is encrypted 0 - data is not encrypted -1 - data encryption is unknown (could be encrypted or not)

func (*SecureData) IsEncryptedBytes ¶

func (s *SecureData) IsEncryptedBytes(data []byte) int

IsEncryptedBytes returns if the given data is encrypted or not. The data is encrypted if it starts with the encryption marker. If an empty string is used as the encryption prefix, then the it can not be reliably checked if the data is enrypted or not. 1 - data is encrypted 0 - data is not encrypted -1 - data encryption is unknown (could be encrypted or not)

func (*SecureData) ToHexString ¶

func (s *SecureData) ToHexString(data []byte) string

func (*SecureData) TryDecryptString ¶

func (s *SecureData) TryDecryptString(data string, passphrase string) (string, error)

TryDecryptString tries to decrypt a string. If a encryption prefex string is used, then the data will only be decrypted if the input data has the prefix, otherwise it will be returned as is.

func (*SecureData) TryEncryptString ¶

func (s *SecureData) TryEncryptString(data string, passphrase string) (string, error)

TryEncryptString encrypts a string only if it is not already encrypted
