Results for: "remove_const"

Fully resets the internal state of the Cipher. By using this, the same Cipher instance may be used several times for encryption or decryption tasks.

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

Resets the Digest in the sense that any Digest#update that has been performed is abandoned and the Digest is set to its initial state again.

Returns hmac as it was when it was first initialized, with all processed data cleared from it.

Example

data = "The quick brown fox jumps over the lazy dog"
instance = OpenSSL::HMAC.new('key', OpenSSL::Digest.new('sha1'))
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f

instance.update(data)
#=> de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9
instance.reset
#=> f42bb0eeb018ebbd4597ae7213711ec60760843f

Parameters

• pass - string

• name - A string describing the key.

• key - Any PKey.

• cert - A X509::Certificate.

  • The public_key portion of the certificate must contain a valid public key.

  • The not_before and not_after fields must be filled in.

• ca - An optional array of X509::Certificate‘s.

• key_pbe - string

• cert_pbe - string

• key_iter - integer

• mac_iter - integer

• keytype - An integer representing an MSIE specific extension.

Any optional arguments may be supplied as nil to preserve the OpenSSL defaults.

See the OpenSSL documentation for PKCS12_create().

Called when an empty event happens. (Which, as far as I can tell, is never).

returns the cmsg level as an integer.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").level
#=> 41

Sends the String msg to the source

returns the socket level as an integer.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).level
#=> 41

Resets and initializes the stream. All data in both input and output buffer are discarded.

Returns compression level.

Resets the position of the file pointer to the point created the GzipReader object. The associated IO object needs to respond to the seek method.

See Zlib::GzipReader documentation for a description.

Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

See Zlib::GzipReader documentation for a description.

Returns an integer representing the permission bits of stat. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

File.chmod(0644, "testfile")   #=> 1
s = File.stat("testfile")
sprintf("%o", s.mode)          #=> "100644"

Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.

file_name can be an IO object.

File.directory?(".")

Returns true if stat is readable by the effective user id of this process.

File.stat("testfile").readable?   #=> true

Returns true if key is registered

Returns the instruction sequence as a String in human readable form.

puts RubyVM::InstructionSequence.compile('1 + 2').disasm

Produces:

== disasm: <RubyVM::InstructionSequence:<compiled>@<compiled>>==========
0000 trace            1                                               (   1)

0004 putobject        2

Takes body, a Method or Proc object, and returns a String with the human readable instructions for body.

For a Method object:

# /tmp/method.rb
def hello
  puts "hello, world"
end

puts RubyVM::InstructionSequence.disasm(method(:hello))

Produces:

== disasm: <RubyVM::InstructionSequence:hello@/tmp/method.rb>============
0000 trace            8                                               (   1)

0004 putself
0005 putstring        "hello, world"
0007 send             :puts, 1, nil, 8, <ic:0>
0013 trace            16                                              (   3)

For a Proc:

# /tmp/proc.rb
p = proc { num = 1 + 2 }
puts RubyVM::InstructionSequence.disasm(p)

Produces:

== disasm: <RubyVM::InstructionSequence:block in <main>@/tmp/proc.rb>===
