Resets the trust directory for verifying gems.
Displays an alert statement. Asks a question if given.
This calls IO.popen where it accepts an array for a command (Ruby 1.9+) and implements an IO.popen-like behavior where it does not accept an array for a command.
SecureRandom.base64 generates a random base64 string.
The argument n specifies the length, in bytes, of the random number to be generated. The length of the result string is about 4/3 of n.
If n is not specified or is nil, 16 is assumed. It may be larger in the future.
The result may contain A-Z, a-z, 0-9, “+”, “/” and “=”.
require 'securerandom' SecureRandom.base64 #=> "/2BuBuLf3+WfSKyQbRcc/A==" SecureRandom.base64 #=> "6BbW0pxO0YENxn38HMUbcQ=="
If a secure random number generator is not available, NotImplementedError is raised.
See RFC 3548 for the definition of base64.
SecureRandom.choose generates a string that randomly draws from a source array of characters.
The argument source specifies the array of characters from which to generate the string. The argument n specifies the length, in characters, of the string to be generated.
The result may contain whatever characters are in the source array.
require 'securerandom' SecureRandom.choose([*'l'..'r'], 16) #=> "lmrqpoonmmlqlron" SecureRandom.choose([*'0'..'9'], 5) #=> "27309"
If a secure random number generator is not available, NotImplementedError is raised.
SecureRandom.alphanumeric generates a random alphanumeric string.
The argument n specifies the length, in characters, of the alphanumeric string to be generated.
If n is not specified or is nil, 16 is assumed. It may be larger in the future.
The result may contain A-Z, a-z and 0-9.
require 'securerandom' SecureRandom.alphanumeric #=> "2BuBuLf3WfSKyQbR" SecureRandom.alphanumeric(10) #=> "i6K93NdqiH"
If a secure random number generator is not available, NotImplementedError is raised.

Set the effective group ID of the calling process to group. Not available on all platforms.
Sets the (user) real and/or effective user IDs of the current process to rid and eid, respectively. A value of -1 for either means to leave that ID unchanged. Not available on all platforms.
Sets the (group) real and/or effective group IDs of the current process to rid and eid, respectively. A value of -1 for either means to leave that ID unchanged. Not available on all platforms.
Sets the (user) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively. A value of -1 for any value means to leave that ID unchanged. Not available on all platforms.
Sets the (group) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively. A value of -1 for any value means to leave that ID unchanged. Not available on all platforms.
Returns true if the process was created as a result of an execve(2) system call which had either of the setuid or setgid bits set (and extra privileges were given as a result) or if it has changed any of its real, effective or saved user or group IDs since it began execution.
