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 if the free function for this pointer has been called.

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

Wakes up all threads waiting for this lock.

Returns the string representation of the bignum.

BN.new can parse the encoded string to convert back into an OpenSSL::BN.

base

The format. Must be one of the following:

• 0 - MPI format. See the man page BN_bn2mpi(3) for details.

• 2 - Variable-length and big-endian binary encoding. The sign of the bignum is ignored.

• 10 - Decimal number representation, with a leading ‘-’ for a negative bignum.

• 16 - Hexadeciaml number representation, with a leading ‘-’ for a negative bignum.

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).

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

Example

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

Returns the authentication code an a Base64-encoded string.

Returns the authentication code as a binary 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.digest('SHA1', 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 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"

Returns the authentication code as a Base64-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.base64digest('SHA1', key, data)
#=> "3nybhbi3iqa8ino29wqQcBydtNk="

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', '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', '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 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"

Gets 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

Returns a new instance of 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'
