uri.to_mailtext
# => "To: ruby-list@ruby-lang.org\nSubject: subscribe\nCc: myaddr\n\n\n"

OpenSSL::PKCS5.pbkdf2_hmac has been renamed to OpenSSL::KDF.pbkdf2_hmac. This method is provided for backwards compatibility.

PKCS #5 PBKDF2 (Password-Based Key Derivation Function 2) in combination with HMAC. Takes pass, salt and iterations, and then derives a key of length bytes.

For more information about PBKDF2, see RFC 2898 Section 5.2 (tools.ietf.org/html/rfc2898#section-5.2).

Parameters

pass

The passphrase.

salt

The salt. Salts prevent attacks based on dictionaries of common passwords and attacks based on rainbow tables. It is a public value that can be safely stored along with the password (e.g. if the derived value is used for password storage).

iterations

The iteration count. This provides the ability to tune the algorithm. It is better to use the highest count possible for the maximum resistance to brute-force attacks.

length

The desired length of the derived key in octets.

hash

The hash algorithm used with HMAC for the PRF. May be a String representing the algorithm name, or an instance of OpenSSL::Digest.

Generates a mask bit for a priority level. See mask=

Generate an Image Button Input element as a string.

src is the URL of the image to use for the button. name is the input name. alt is the alternative text for the image.

Alternatively, the attributes can be specified as a hash.

image_button("url")
  # <INPUT TYPE="image" SRC="url">

image_button("url", "name", "string")
  # <INPUT TYPE="image" SRC="url" NAME="name" ALT="string">

image_button("SRC" => "url", "ALT" => "string")
  # <INPUT TYPE="image" SRC="url" ALT="string">

Returns a content type string such as “text”. This method returns nil if Content-Type: header field does not exist.

A convenience method which is same as follows:

text ','
breakable

Wraps text to wrap characters and optionally indents by indent characters

Specifies Emacs editing mode. The default is this mode. See the manual of GNU Readline for details of Emacs editing mode.

Raises NotImplementedError if the using readline library does not support.

Returns true if emacs mode is active. Returns false if not.

Raises NotImplementedError if the using readline library does not support.

Returns the size of memory allocated by malloc().

Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.

Deduce Ruby’s –program-prefix and –program-suffix from its install name

Returns true if the MKD command may be used to create a new directory within the directory.

Returns true if other is a subdomain.

Example:

domain = Resolv::DNS::Name.create("y.z")
p Resolv::DNS::Name.create("w.x.y.z").subdomain_of?(domain) #=> true
p Resolv::DNS::Name.create("x.y.z").subdomain_of?(domain) #=> true
p Resolv::DNS::Name.create("y.z").subdomain_of?(domain) #=> false
p Resolv::DNS::Name.create("z").subdomain_of?(domain) #=> false
p Resolv::DNS::Name.create("x.y.z.").subdomain_of?(domain) #=> false
p Resolv::DNS::Name.create("w.z").subdomain_of?(domain) #=> false
