Results for: "remove_const"

Return the data hash computed with name Digest. name is either the long name or short name of a supported digest algorithm.

Examples

OpenSSL::Digest.digest("SHA256", "abc")

which is equivalent to:

OpenSSL::Digest::SHA256.digest("abc")

This returns an OpenSSL::Digest by name.

Will raise an EngineError if the digest is unavailable.

e = OpenSSL::Engine.by_id("openssl")
  #=> #<OpenSSL::Engine id="openssl" name="Software engine support">
e.digest("SHA1")
  #=> #<OpenSSL::Digest: da39a3ee5e6b4b0d3255bfef95601890afd80709>
e.digest("zomg")
  #=> OpenSSL::Engine::EngineError: no such digest `zomg'

Pretty print this engine

Returns the authentication code as a binary string. The digest parameter must be an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'
digest = OpenSSL::Digest.new('sha1')

hmac = OpenSSL::HMAC.digest(digest, key, data)
#=> "\xDE|\x9B\x85\xB8\xB7\x8A\xA6\xBC\x8Az6\xF7\n\x90p\x1C\x9D\xB4\xD9"

Returns the authentication code as a hex-encoded string. The digest parameter must be an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'
digest = OpenSSL::Digest.new('sha1')

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

Returns the authentication code an instance represents as a binary string.

Example

instance = OpenSSL::HMAC.new('key', OpenSSL::Digest.new('sha1'))
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f
instance.digest
#=> "\xF4+\xB0\xEE\xB0\x18\xEB\xBDE\x97\xAEr\x13q\x1E\xC6\a`\x84?"

Returns the authentication code an instance represents as a hex-encoded string.

Returns the authentication code as a hex-encoded string. The digest parameter must be an instance of OpenSSL::Digest.

Example

key = 'key'
data = 'The quick brown fox jumps over the lazy dog'
digest = OpenSSL::Digest.new('sha1')

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

Returns the exit status of the child for which PTY#check raised this exception

The column number of the current token. This value starts from 0. This method is valid only in event handlers.

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 the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.

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>"

Returns comments recorded in the gzip file header, or nil if the comments is not present.

Specify the comment (str) in the gzip header.

Produce a nicely formatted description of stat.

File.stat("/etc/passwd").inspect
   #=> "#<File::Stat dev=0xe000005, ino=1078078, mode=0100644,
   #    nlink=1, uid=0, gid=0, rdev=0x0, size=1374, blksize=4096,
   #    blocks=8, atime=Wed Dec 10 10:16:12 CST 2003,
   #    mtime=Fri Sep 12 15:41:41 CDT 2003,
   #    ctime=Mon Oct 27 11:20:27 CST 2003,
   #    birthtime=Mon Aug 04 08:13:49 CDT 2003>"

Returns true if stat has its sticky bit set, false if it doesn’t or if the operating system doesn’t support this feature.

File.stat("testfile").sticky?   #=> false

Returns a human-readable string representation of this instruction sequence, including the label and path.

Takes source, a String of Ruby code and compiles it to an InstructionSequence.

Optionally takes file, path, and line which describe the filename, absolute path and first line number of the ruby code in source which are metadata attached to the returned iseq.

options, which can be true, false or a Hash, is used to modify the default behavior of the Ruby iseq compiler.

For details regarding valid compile options see ::compile_option=.

RubyVM::InstructionSequence.compile("a = 1 + 2")
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>

Set whether the Cookie is a httponly cookie or not.

val must be a boolean.

A summary of cookie string.

A summary of fields, by header, in an ASCII compatible String.
