Sets the key length of the cipher. If the cipher is a fixed length cipher then attempting to set the key length to any value other than the fixed value is an error.

Under normal circumstances you do not need to call this method (and probably shouldn’t).

See EVP_CIPHER_CTX_set_key_length for further information.

Returns the key length in bytes of the Cipher.

Sets the IV/nonce length of the Cipher. Normally block ciphers don’t allow changing the IV length, but some make use of IV for ‘nonce’. You may need this for interoperability with other applications.

Returns the expected length in bytes for an IV for this Cipher.

Returns the output size of the digest, i.e. the length in bytes of the final message digest result.

Example

digest = OpenSSL::Digest.new('SHA1')
puts digest.digest_length # => 20

Returns the block length of the digest algorithm, i.e. the length in bytes of an individual block. Most modern algorithms partition a message to be digested into a sequence of fix-sized blocks that are processed consecutively.

Example

digest = OpenSSL::Digest.new('SHA1')
puts digest.block_length # => 64

Set the defaults for this engine with the given flag.

These flags are used to control combinations of algorithm methods.

flag can be one of the following, other flags are available depending on your OS.

All flags

0xFFFF

No flags

0x0000

Builds a methods for level meth.

Delete a registry value named name. We can not delete the ‘default’ value.

Delete a subkey named name and all its values.

If recursive is false, the subkey must not have subkeys. Otherwise, this method deletes all subkeys and values recursively.

Returns OLE type of WIN32OLE_PARAM object(parameter of OLE method).

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
param1 = method.params[0]
puts param1.ole_type # => VARIANT

Returns value specified by the member name of VT_RECORD OLE variable. Or sets value specified by the member name of VT_RECORD OLE variable. If the member name is not correct, KeyError exception is raised.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
End Class

Then getting/setting value from Ruby is as the following:

obj = WIN32OLE.new('ComServer.ComClass')
book = WIN32OLE_RECORD.new('Book', obj)
book.title # => nil ( book.method_missing(:title) is invoked. )
book.title = "Ruby" # ( book.method_missing(:title=, "Ruby") is invoked. )

Returns array of WIN32OLE_TYPE objects defined by the typelib type library. This method will be OBSOLETE. Use WIN32OLE_TYPELIB.new(typelib).ole_classes instead.

returns type of OLE class.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application')
puts tobj.ole_type  # => Class

Returns the WIN32OLE_TYPELIB object which is including the WIN32OLE_TYPE object. If it is not found, then returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
puts tobj.ole_typelib # => 'Microsoft Excel 9.0 Object Library'

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns OLE type string.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.ole_type} #{variable.name}"
end

The result of above script is following:
  INT xlChart
  INT xlDialogSheet
  INT xlExcel4IntlMacroSheet
  INT xlExcel4MacroSheet
  INT xlWorksheet

Returns variable kind string.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.name} #{variable.variable_kind}"
end

The result of above script is following:
  xlChart CONSTANT
  xlDialogSheet CONSTANT
  xlExcel4IntlMacroSheet CONSTANT
  xlExcel4MacroSheet CONSTANT
  xlWorksheet CONSTANT

Returns OS code number recorded in the gzip file header.

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

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

If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/etc/passwd").world_readable?  #=> 420
sprintf("%o", m)                              #=> "644"

Returns true if stat is writable by the real user id of this process.

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