Results for: "fnmatch"

Generates new parameters for the algorithm. algo_name is a String that represents the algorithm. The optional argument options is a Hash that specifies the options specific to the algorithm. The order of the options can be important.

A block can be passed optionally. The meaning of the arguments passed to the block varies depending on the implementation of the algorithm. The block may be called once or multiple times, or may not even be called.

For the supported options, see the documentation for the ‘openssl genpkey’ utility command.

Example

pkey = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048)
p pkey.p.num_bits #=> 2048

Generates a new key (pair).

If a String is given as the first argument, it generates a new random key for the algorithm specified by the name just as ::generate_parameters does. If an OpenSSL::PKey::PKey is given instead, it generates a new random key for the same algorithm as the key, using the parameters the key contains.

See ::generate_parameters for the details of options and the given block.

Example

pkey_params = OpenSSL::PKey.generate_parameters("DSA", "dsa_paramgen_bits" => 2048)
pkey_params.priv_key #=> nil
pkey = OpenSSL::PKey.generate_key(pkey_params)
pkey.priv_key #=> #<OpenSSL::BN 6277...

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=

Returns an Array of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME.

For example:

[
  {
     :GC_TIME=>1.3000000000000858e-05,
     :GC_INVOKE_TIME=>0.010634999999999999,
     :HEAP_USE_SIZE=>289640,
     :HEAP_TOTAL_SIZE=>588960,
     :HEAP_TOTAL_OBJECTS=>14724,
     :GC_IS_MARKED=>false
  },
  # ...
]

The keys mean:

:GC_TIME

Time elapsed in seconds for this GC run

:GC_INVOKE_TIME

Time elapsed in seconds from startup to when the GC was invoked

:HEAP_USE_SIZE

Total bytes of heap used

:HEAP_TOTAL_SIZE

Total size of heap in bytes

:HEAP_TOTAL_OBJECTS

Total number of objects

:GC_IS_MARKED

Returns true if the GC is in mark phase

If ruby was built with GC_PROFILE_MORE_DETAIL, you will also have access to the following hash keys:

:GC_MARK_TIME

:GC_SWEEP_TIME

:ALLOCATE_INCREASE

:ALLOCATE_LIMIT

:HEAP_USE_PAGES

:HEAP_LIVE_OBJECTS

:HEAP_FREE_OBJECTS

:HAVE_FINALIZE

Generate a sequence of checkbox elements, as a String.

The checkboxes will all have the same name attribute. Each checkbox is followed by a label. There will be one checkbox for each value. Each value can be specified as a String, which will be used both as the value of the VALUE attribute and as the label for that checkbox. A single-element array has the same effect.

Each value can also be specified as a three-element array. The first element is the VALUE attribute; the second is the label; and the third is a boolean specifying whether this checkbox is CHECKED.

Each value can also be specified as a two-element array, by omitting either the value element (defaults to the same as the label), or the boolean checked element (defaults to false).

checkbox_group("name", "foo", "bar", "baz")
  # <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo
  # <INPUT TYPE="checkbox" NAME="name" VALUE="bar">bar
  # <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz

checkbox_group("name", ["foo"], ["bar", true], "baz")
  # <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo
  # <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="bar">bar
  # <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz

checkbox_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz")
  # <INPUT TYPE="checkbox" NAME="name" VALUE="1">Foo
  # <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="2">Bar
  # <INPUT TYPE="checkbox" NAME="name" VALUE="Baz">Baz

checkbox_group("NAME" => "name",
                 "VALUES" => ["foo", "bar", "baz"])

checkbox_group("NAME" => "name",
                 "VALUES" => [["foo"], ["bar", true], "baz"])

checkbox_group("NAME" => "name",
                 "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])

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">

Calls the block with each key/value pair:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_header do |key, value|
  p [key, value] if key.start_with?('c')
end

Output:

["content-type", "application/json; charset=utf-8"]
["connection", "keep-alive"]
["cache-control", "max-age=43200"]
["cf-cache-status", "HIT"]
["cf-ray", "771d17e9bc542cf5-ORD"]

Returns an enumerator if no block is given.

Net::HTTPHeader#each is an alias for Net::HTTPHeader#each_header.

Calls the block with each field key:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_key do |key|
  p key if key.start_with?('c')
end

Output:

"content-type"
"connection"
"cache-control"
"cf-cache-status"
"cf-ray"

Returns an enumerator if no block is given.

Net::HTTPHeader#each_name is an alias for Net::HTTPHeader#each_key.

Calls the block with each string field value:

res = Net::HTTP.get_response(hostname, '/todos/1')
res.each_value do |value|
  p value if value.start_with?('c')
end

Output:

"chunked"
"cf-q-config;dur=6.0000002122251e-06"
"cloudflare"

Returns an enumerator if no block is given.

Like each_header, but the keys are returned in capitalized form.

Net::HTTPHeader#canonical_each is an alias for Net::HTTPHeader#each_capitalized.

Returns the leading (‘type’) part of the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['content-type'] # => "application/json; charset=utf-8"
res.main_type       # => "application"

A convenience method which is same as follows:

breakable

Creates an unsigned certificate for subject and key. The lifetime of the key is from the current time to age which defaults to one year.

The extensions restrict the key to the indicated uses.

Creates a new key pair of the specified algorithm. RSA, DSA, and EC are supported.

Enumerates the trusted certificates via Gem::Security::TrustDir.

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the Rubygems version that it is planned to go away.
