Results for: "pstore"

Returns the hash value of a given string. This is equivalent to Digest::Class.new(*parameters).digest(string), where extra parameters, if any, are passed through to the constructor and the string is passed to digest().

Returns the hex-encoded hash value of a given string. This is almost equivalent to Digest.hexencode(Digest::Class.new(*parameters).digest(string)).

Returns the base64 encoded hash value of a given string. The return value is properly padded with ‘=’ and contains no line feeds.

Returns the memory address for this closure

The integer memory location of this function

Returns the memory address for this handle.

Set the free function for this pointer to function in the given Fiddle::Function.

Get the free function for this pointer.

Returns a new instance of Fiddle::Function.

See Fiddle::Function.new

Returns the integer memory location of this pointer.

Returns a new Fiddle::Pointer instance that is a reference pointer for this pointer.

Analogous to the ampersand operator in C.

ptr.to_s        => string
ptr.to_s(len)   => string

Returns the pointer contents as a string.

When called with no arguments, this method will return the contents until the first NULL byte.

When called with len, a string of len bytes will be returned.

See to_str

Parameters

• base - integer

• • Valid values:

• • • 0 - MPI

• • • 2 - binary

• • • 10 - the default

• • • 16 - hex

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).

Get the parsable form of the current configuration

Given the following configuration being created:

config = OpenSSL::Config.new
  #=> #<OpenSSL::Config sections=[]>
config['default'] = {"foo"=>"bar","baz"=>"buz"}
  #=> {"foo"=>"bar", "baz"=>"buz"}
puts config.to_s
  #=> [ default ]
  #   foo=bar
  #   baz=buz

You can parse get the serialized configuration using to_s and then parse it later:

serialized_config = config.to_s
# much later...
new_config = OpenSSL::Config.parse(serialized_config)
  #=> #<OpenSSL::Config sections=["default"]>
puts new_config
  #=> [ default ]
      foo=bar
      baz=buz

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")

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.

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'

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 self 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

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.
