func CeilInt64 ¶

func CeilInt64(x float64) int64

func CeilUint64 ¶

func CeilUint64(x float64) uint64

func Decrypt ¶

func Decrypt(key []byte, iv []byte, ciphertext []byte) ([]byte, error)

func Encrypt ¶

func Encrypt(key []byte, iv []byte, cleartext []byte) ([]byte, error)

One-off encryption and decryption. This is not meant for huge chunks of data.

func GenAESKey ¶

func GenAESKey() []byte

func GenIV ¶

func GenIV() []byte

func GenKey ¶

func GenKey(length int) []byte

Generate a key (random bytes) of the given length (in bytes).

func IncrementBytes ¶

func IncrementBytes(bytes []byte)

"Increment" the byte silce by going through each byte (big endian) and incremnt it. If the byte does not roll over to zero, then stop there.

func IncrementBytesByCount ¶

func IncrementBytesByCount(bytes []byte, count int)

func MaxInt ¶

func MinInt ¶

func MinInt(a int, b int) int

func MinInt64 ¶

func MinInt64(a int64, b int64) int64

func RandomBytes ¶

func RandomBytes(length int) []byte

func RandomString ¶

func RandomString(length int) string

func SHA256Hex ¶

func SHA256Hex(val string) string

Get the SHA2-256 string.

func ScanInt ¶

func ScanInt(scanner *bufio.Scanner) (int, error)

Will Scan() the scanner once and read the contents as a string.

func SliceHasString ¶

func SliceHasString(haystack []string, needle string) bool

Uses standard n search and equality.

func Weakhash ¶

func Weakhash(username string, password string) string

Generate a password hash the same way that clients are expected to.
