Returns the number that defines the first element of this arithmetic sequence.
Returns the number that defines the common difference between two adjacent elements in this arithmetic sequence.
Returns the first number in this arithmetic sequence, or an array of the first n elements.
Returns the last number in this arithmetic sequence, or an array of the last n elements.
Convert this arithmetic sequence to a printable form.
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 a new Fiddle::Pointer instance that is a dereferenced pointer for this pointer.
Analogous to the star operator in C.
Returns a string formatted with an easily readable representation of the internal state of the pointer.
Wakes up all threads waiting for this lock.
Performs a Miller-Rabin probabilistic primality test with checks iterations. If checks is not specified, a number of iterations is used that yields a false positive rate of at most 2^-80 for random input.
checks - integer
Returns the remaining data held in the cipher object. Further calls to Cipher#update or Cipher#final will return garbage. This call should always be made as the last call of an encryption or decryption operation, after having fed the entire plaintext or ciphertext to the Cipher instance.
If an authenticated cipher was used, a CipherError is raised if the tag could not be authenticated successfully. Only call this method after setting the authentication tag and passing the entire contents of the ciphertext into the cipher.
String representation of this configuration object, including the class name and its sections.
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")
Releases all internal structural references for this engine.
May raise an EngineError if the engine is unavailable
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'
Pretty prints this engine.
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.
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"
