Imports of package rand

PathSynopsis
bufioPackage bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O.
crypto/aesPackage aes implements AES encryption (formerly Rijndael), as defined in U.S. Federal Information Processing Standards Publication 197.
crypto/cipherPackage cipher implements standard block cipher modes that can be wrapped around low-level block cipher implementations.
errorsPackage errors implements functions to manipulate errors.
internal/syscall/unix
ioPackage io provides basic interfaces to I/O primitives.
math/bigPackage big implements arbitrary-precision arithmetic (big numbers).
osPackage os provides a platform-independent interface to operating system functionality.
runtimePackage runtime contains operations that interact with Go's runtime system, such as functions to control goroutines.
syncPackage sync provides basic synchronization primitives such as mutual exclusion locks.
syscallPackage syscall contains an interface to the low-level operating system primitives.
timePackage time provides functionality for measuring and displaying time.
