Checks if there are duplicate links with the same type and hreflang attributes that have an alternate (or empty) rel attribute
Raises a TooMuchTagError if there are duplicates found
Update the digest using given string and return self.
Performs a Miller-Rabin probabilistic primality test with checks iterations. If nchecks 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
Encrypts data in a streaming fashion. Hand consecutive blocks of data to the update method in order to encrypt it. Returns the encrypted data chunk. When done, the output of Cipher#final should be additionally added to the result.
If buffer is given, the encryption/decryption result will be written to it. buffer will be resized automatically.
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.
Enables or disables padding. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the pad parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.
See EVP_CIPHER_CTX_set_padding for further information.
Parses a given string as a blob that contains configuration for openssl.
If the source of the IO is a file, then consider using parse_config.
Not every message digest can be computed in one single pass. If a message digest is to be computed from several subsequent sources, then each may be passed individually to the Digest instance.
digest = OpenSSL::Digest::SHA256.new digest.update('First input') digest << 'Second input' # equivalent to digest.update('Second input') result = digest.digest
Returns self updated with the message to be authenticated. Can be called repeatedly with chunks of the message.
first_chunk = 'The quick brown fox jumps ' second_chunk = 'over the lazy dog' instance.update(first_chunk) #=> 5b9a8038a65d571076d97fe783989e52278a492a instance.update(second_chunk) #=> de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9
pass - string
name - A string describing the key.
key - Any PKey.
cert - A X509::Certificate.
The public_key portion of the certificate must contain a valid public key.
The not_before and not_after fields must be filled in.
ca - An optional array of X509::Certificate‘s.
key_pbe - string
cert_pbe - string
key_iter - integer
mac_iter - integer
keytype - An integer representing an MSIE specific extension.
Any optional arguments may be supplied as nil to preserve the OpenSSL defaults.
See the OpenSSL documentation for PKCS12_create().
Is this handler a streaming handler?
Returns the exit status of the child for which PTY#check raised this exception
Another entry point for the parser. If you use this method, you must implement RECEIVER#METHOD_ID method.
RECEIVER#METHOD_ID is a method to get next token. It must ‘yield’ the token, which format is [TOKEN-SYMBOL, VALUE].
Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).
returns the socket family as an integer.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").family #=> 10
returns the cmsg data as a string.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").data #=> ""
returns the socket family as an integer.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).family #=> 10
returns the socket option data as a string.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data #=> "\x01\x00\x00\x00"
Calls String#unpack on sockopt.data.
sockopt = Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")) p sockopt.unpack("i") #=> [1] p sockopt.data.unpack("i") #=> [1]
