Fully resets the internal state of the Cipher. By using this, the same Cipher instance may be used several times for encryption or decryption tasks.
Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, -1).
Initializes the Cipher for encryption.
Make sure to call Cipher#encrypt or Cipher#decrypt before using any of the following methods:
Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, 1).
Initializes the Cipher for decryption.
Make sure to call Cipher#encrypt or Cipher#decrypt before using any of the following methods:
Internally calls EVP_CipherInit_ex(ctx, NULL, NULL, NULL, NULL, 0).
Indicated whether this Cipher instance uses an Authenticated Encryption mode.
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.
Resets the Digest in the sense that any Digest#update that has been performed is abandoned and the Digest is set to its initial state again.
Returns the authentication code an a Base64-encoded string.
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 hmac as it was when it was first initialized, with all processed data cleared from it.
data = "The quick brown fox jumps over the lazy dog" instance = OpenSSL::HMAC.new('key', 'SHA1') #=> f42bb0eeb018ebbd4597ae7213711ec60760843f instance.update(data) #=> de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9 instance.reset #=> f42bb0eeb018ebbd4597ae7213711ec60760843f
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>
Creates a PKCS #7 enveloped-data structure.
Before version 3.3.0, cipher was optional and defaulted to "RC2-40-CBC".
See also the man page PKCS7_encrypt(3).
Convert path string to a class
Emit a scalar with value
Emit a sequence of list
Called when a scalar value is found. The scalar may have an anchor, a tag, be implicitly plain or implicitly quoted
value is the string value of the scalar anchor is an associated anchor or nil tag is an associated tag or nil plain is a boolean value quoted is a boolean value style is an integer indicating the string style
See the constants in Psych::Nodes::Scalar for the possible values of style
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !str "foo" - &anchor fun - many lines - | many newlines
The above YAML document contains a list with four strings. Here are the parameters sent to this method in the same order:
# value anchor tag plain quoted style ["foo", nil, "!str", false, false, 3 ] ["fun", "anchor", nil, true, false, 1 ] ["many lines", nil, nil, true, false, 1 ] ["many\nnewlines\n", nil, nil, false, true, 4 ]
Called when an empty event happens. (Which, as far as I can tell, is never).
Returns a Psych::Parser::Mark object that contains line, column, and index information.
Emit a scalar with value, anchor, tag, and a plain or quoted string type with style.
Get the output style, canonical or not.
