This is a deprecated alias for each_byte.

Returns a random binary string containing size bytes.

random_string = Random.new.bytes(10) # => "\xD7:R\xAB?\x83\xCE\xFAkO"
random_string.size                   # => 10

Returns a random binary string. The argument size specifies the length of the returned string.

Creates a new Socket::Option object which contains a byte as data.

p Socket::Option.byte(:INET, :SOCKET, :KEEPALIVE, 1)
#=> #<Socket::Option: INET SOCKET KEEPALIVE 1>

Returns the data in sockopt as an byte.

sockopt = Socket::Option.byte(:INET, :SOCKET, :KEEPALIVE, 1)
p sockopt.byte => 1

See Zlib::GzipReader documentation for a description.

True if version satisfies this Requirement.

Returns the total size in bytes of all the messages on the POP server.

Returns the discarded bytes when Encoding::InvalidByteSequenceError occurs.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")
begin
  ec.convert("abc\xA1\xFFdef")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "\xFF" on EUC-JP>
  puts $!.error_bytes.dump          #=> "\xA1"
  puts $!.readagain_bytes.dump      #=> "\xFF"
end

Returns the bytes to be read again when Encoding::InvalidByteSequenceError occurs.

Calls the given block once for each byte in the stream.

Generates a String with length number of cryptographically strong pseudo-random bytes.

Example

OpenSSL::Random.random_bytes(12)
#=> "..."

Generates a String with length number of pseudo-random bytes.

Pseudo-random byte sequences generated by ::pseudo_bytes will be unique if they are of sufficient length, but are not necessarily unpredictable.

Example

OpenSSL::Random.pseudo_bytes(12)
#=> "..."

Queries the entropy gathering daemon EGD on socket path given by filename.

Fetches length number of bytes and uses ::add to seed the OpenSSL built-in PRNG.

SecureRandom.random_bytes generates a random binary string.

The argument n specifies the length of the result string.

If n is not specified or is nil, 16 is assumed. It may be larger in future.

The result may contain any byte: “x00” - “xff”.

require 'securerandom'

SecureRandom.random_bytes #=> "\xD8\\\xE0\xF4\r\xB2\xFC*WM\xFF\x83\x18\xF45\xB6"
SecureRandom.random_bytes #=> "m\xDC\xFC/\a\x00Uf\xB2\xB2P\xBD\xFF6S\x97"

If a secure random number generator is not available, NotImplementedError is raised.

@param [Object] requirement @param [DependencyGraph] activated the current dependency graph in the

resolution process.

@param [Object] spec @return [Boolean] whether ‘requirement` is satisfied by `spec` in the
