Allocates a C union the types
provided.
When the instance is garbage collected, the C function func
is called.
Fiddle::Pointer.malloc(size, freefunc = nil) => fiddle pointer instance
Allocate size
bytes of memory and associate it with an optional freefunc
that will be called when the pointer is garbage collected.
freefunc
must be an address pointing to a function or an instance of Fiddle::Function
Returns the names of all available ciphers in an array.
Return the hash value computed with name Digest
. name is either the long name or short name of a supported digest algorithm.
OpenSSL::Digest.digest("SHA256", "abc")
which is equivalent to:
OpenSSL::Digest::SHA256.digest("abc")
This method loads engines. If name is nil, then all builtin engines are loaded. Otherwise, the given name, as a String
, is loaded if available to your runtime, and returns true. If name is not found, then nil is returned.
Returns a new instance of OpenSSL::Cipher
by name, if it is available in this engine.
An EngineError
will be raised if the cipher is unavailable.
e = OpenSSL::Engine.by_id("openssl") => #<OpenSSL::Engine id="openssl" name="Software engine support"> e.cipher("RC4") => #<OpenSSL::Cipher:0x007fc5cacc3048>
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'
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
.
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
.
key = 'key' data = 'The quick brown fox jumps over the lazy dog' hmac = OpenSSL::HMAC.hexdigest('sha1', key, data) #=> "de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9"
Returns the authentication code an instance represents as a binary string.
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.
Enter error recovering mode. This method does not call on_error
.
Leave error recovering mode.
Returns the adler-32 checksum.
Returns true if the stream is closed.
Closes the stream. All operations on the closed stream will raise an exception.
Closes the GzipFile
object. This method calls close method of the associated IO
object. Returns the associated IO
object.
