Instance Method Details

#array_first_remainder(args = ARGV) ⇒ Object

this class very often needs to split first argument and remaining elements. args: args default: ARGV returns:

args, args[1..-1

]

# File 'lib/rubyment.rb', line 20

def array_first_remainder args=ARGV
  [ args[0], args[1..-1] ]
end

#containerize(args = ARGV) ⇒ Object

returns a Class object out of class_name (or itself if it is already a class)

# File 'lib/rubyment.rb', line 112

def containerize args=ARGV
  [args].flatten 1
end

#dec(args = ARGV) ⇒ Object

decrypt encrypted (string), having password (string), iv (string), big_file(bool) is a flag to set padding to 0.

planned changes: add metadata information to encrypted decipher.key = Digest::SHA256.hexdigest is not the best security. encrypted could be called base64_encrypted iv could be called base64_iv get only one string, not encrypted and iv (see enc planned changes) remove dependence on the uniqueness of ending

#deserialize_json_metadata(args = ARGV) ⇒ Object

deserialize_json_metadata args:

serialized_string (String), separator (String)

undo what serialize_json_metadata returns array:

payload (String), metadata (Hash or String), separator (String)

metadata is returned as Hash after a JSON.parse, but in case of any failure, it returns the String itself.

#enc(args = ARGV) ⇒ Object

encrypt data (string), with password (string) returns [base64_iv, base64_encrypted]

planned changes: add metadata information to encrypted return only one string, having encrypted + metadata (having iv) add string length to metadata decipher.key = Digest::SHA256.hexdigest is not the best security.
