Create a new closure. If a block is given, the created closure is automatically freed after the given block is executed.
The all given arguments are passed to Fiddle::Closure.new. So using this method without block equals to Fiddle::Closure.new.
Fiddle::Closure.create(TYPE_INT, [TYPE_INT]) do |closure| # closure is freed automatically when this block is finished. end
Wakes up the first thread in line 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.
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.
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.new('SHA256') digest.update('First input') digest << 'Second input' # equivalent to digest.update('Second input') result = digest.digest
Returns hmac 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
Parses a given string as a blob that contains configuration for OpenSSL.
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?
Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.
See Psych::Parser and Psych::Parser#handler
Get the indentation level.
Set the indentation level to level. The level must be less than 10 and greater than 1.
Returns the exit status of the child for which PTY#check raised this exception
The scanner’s state of the current token. This value is the bitwise OR of zero or more of the Ripper::EXPR_* constants.
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
