Convert this arithmetic sequence to a printable form.

Returns a string formatted with an easily readable representation of the internal state of the pointer.

See Object#inspect.

Initializes the Cipher for encryption.

Make sure to call Cipher#encrypt or Cipher#decrypt before using any of the following methods:

• key=, iv=, random_key, random_iv, pkcs5_keyivgen

Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, 1).

Indicated whether this Cipher instance uses an Authenticated Encryption mode.

String representation of this configuration object, including the class name and its sections.

Pretty prints this engine.

Returns the authentication code as a hex-encoded string. The digest parameter specifies the digest algorithm to use. This may be a String representing the algorithm name or an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'

hmac = OpenSSL::HMAC.hexdigest('sha1', key, data)
#=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"

Get the output style, canonical or not.

Set the output style to canonical, or not.

returns a string which shows ancillarydata in human-readable form.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").inspect
#=> "#<Socket::AncillaryData: INET6 IPV6 PKTINFO \"\">"

returns the timestamp as a time object.

ancillarydata should be one of following type:

• SOL_SOCKET/SCM_TIMESTAMP (microsecond) GNU/Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOS X

• SOL_SOCKET/SCM_TIMESTAMPNS (nanosecond) GNU/Linux

• SOL_SOCKET/SCM_BINTIME (2**(-64) second) FreeBSD

  Addrinfo.udp(“127.0.0.1”, 0).bind {|s1|

  Addrinfo.udp("127.0.0.1", 0).bind {|s2|
    s1.setsockopt(:SOCKET, :TIMESTAMP, true)
    s2.send "a", 0, s1.local_address
    ctl = s1.recvmsg.last
    p ctl    #=> #<Socket::AncillaryData: INET SOCKET TIMESTAMP 2009-02-24 17:35:46.775581>
    t = ctl.timestamp
    p t      #=> 2009-02-24 17:35:46 +0900
    p t.usec #=> 775581
    p t.nsec #=> 775581000
  }
  

  }

Returns a string to show contents of ifaddr.

Returns a string which shows sockopt in human-readable form.

p Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")).inspect
#=> "#<Socket::Option: INET SOCKET KEEPALIVE 1>"

Calls String#unpack on sockopt.data.

sockopt = Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i"))
p sockopt.unpack("i")      #=> [1]
p sockopt.data.unpack("i") #=> [1]

Logs a message at the unknown (syslog alert) log level, or logs the message returned from the block.

Inputs string into the end of input buffer and skips data until a full flush point can be found. If the point is found in the buffer, this method flushes the buffer and returns false. Otherwise it returns true and the following data of full flush point is preserved in the buffer.

Returns last modification time recorded in the gzip file header.

Same as IO#sync

Same as IO. If flag is true, the associated IO object must respond to the flush method. While sync mode is true, the compression ratio decreases sharply.
