Returns URL-escaped string following RFC 3986.
Returns URL-unescaped string following RFC 3986.
URL-encode a string following RFC 3986 Space characters (+“ ”+) are encoded with (+“%20”+)
url_encoded_string = CGI.escape("'Stop!' said Fred") # => "%27Stop%21%27%20said%20Fred"
URL-decode a string following RFC 3986 with encoding(optional).
string = CGI.unescape("%27Stop%21%27+said%20Fred") # => "'Stop!'+said Fred"
If none is given, returns the resulting hash value of the digest, keeping the digest’s state.
If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.
Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
If a string
is given, returns the hash value for the given string
in a base64 encoded form, resetting the digest to the initial state before and after the process.
In either case, the return value is properly padded with ‘=’ and contains no line feeds.
Returns the resulting hash value and resets the digest to the initial state.
Writes s to the stream. If the argument is not a String
it will be converted using .to_s
method. Returns the number of bytes written.
Formats and writes to the stream converting parameters under control of the format string.
See Kernel#sprintf
for format string details.
If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):
depth: The recursion depth, plus one with each constructed value being encountered (Integer
)
offset: Current byte offset (Integer
)
header length: Combined length in bytes of the Tag and Length headers. (Integer
)
length: The overall remaining length of the entire data (Integer
)
constructed: Whether this value is constructed or not (Boolean)
tag_class: Current tag class (Symbol
)
tag: The current tag number (Integer
)
der = File.binread('asn1data.der') OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag| puts "Depth: #{depth} Offset: #{offset} Length: #{length}" puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}" end
Return true
if the PRNG has been seeded with enough data, false
otherwise.
Start streaming using encoding
Returns whether the form contained multipart/form-data
Adds a separated list. The list is separated by comma with breakable space, by default.
seplist
iterates the list
using iter_method
. It yields each object to the block given for seplist
. The procedure separator_proc
is called between each yields.
If the iteration is zero times, separator_proc
is not called at all.
If separator_proc
is nil or not given, +lambda { comma_breakable
}+ is used. If iter_method
is not given, :each is used.
For example, following 3 code fragments has similar effect.
q.seplist([1,2,3]) {|v| xxx v } q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v } xxx 1 q.comma_breakable xxx 2 q.comma_breakable xxx 3
