Constructs a new source range by finding the given character between the given start offset and end offset. If the needle is not found, it returns nil. Importantly it does not search past newlines or comments.
Note that end_offset is allowed to be nil, in which case this will search until the end of the string.
Rewinds the enumerator chain by calling the “rewind” method on each enumerable in reverse order. Each call is performed only if the enumerable responds to the method.
Returns a printable version of the enumerator chain.
Rewinds the product enumerator by calling the “rewind” method on each enumerable in reverse order. Each call is performed only if the enumerable responds to the method.
Returns a printable version of the product enumerator.
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.
Wakes up all threads waiting for this lock.
Performs a Miller-Rabin probabilistic primality test for bn.
checks parameter is deprecated in version 3.0. It has no effect.
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.
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")
Returns the names of all available digests in an array.
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.
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 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.
key = 'key' data = 'The quick brown fox jumps over the lazy dog' hmac = OpenSSL::HMAC.base64digest('SHA1', key, data) #=> "3nybhbi3iqa8ino29wqQcBydtNk="
Returns the authentication code an instance represents as a binary string.
instance = OpenSSL::HMAC.new('key', 'SHA1') #=> f42bb0eeb018ebbd4597ae7213711ec60760843f instance.digest #=> "\xF4+\xB0\xEE\xB0\x18\xEB\xBDE\x97\xAEr\x13q\x1E\xC6\a`\x84?"
