# The ESAPI validator does many security checks on input, such as canonicalization
# and whitelist validation. Note that all of these validation rules are applied *after*
# canonicalization. Double-encoded characters (even with different encodings involved,
# are never allowed.
#
# To use:
#
# First set up a pattern below. You can choose any name you want, prefixed by the word
# "Validation." For example:
# Validation.Email=^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\\.[a-zA-Z]{2,4}$
#
# Then you can validate in your code against the pattern like this:
# ESAPI.validator().isValidInput("User Email", input, "Email", maxLength, allowNull);
# Where maxLength and allowNull are set for you needs, respectively.
#
# But note, when you use boolean variants of validation functions, you lose critical
# canonicalization. It is preferable to use the "get" methods (which throw exceptions) and
# and use the returned user input which is in canonical form. Consider the following:
#
# try {
# someObject.setEmail(ESAPI.validator().getValidInput("User Email", input, "Email", maxLength, allowNull));
#
Validator.SafeString=^[.\\p{Alnum}\\p{Space}]{0,1024}$
#Given the discussion: https://github.com/ESAPI/esapi-java-legacy/issues/374, a better upper-bound for domain name
#was selected as 62. This is slightly under the length in RFC-1035
Validator.Email=^[A-Za-z0-9._%'-]+@[A-Za-z0-9.-]+\\.[a-zA-Z]{2,62}$
Validator.Gmail=^[A-Za-z0-9._%'-+]+@[A-Za-z0-9.-]+\\.[a-zA-Z]{2,62}$
Validator.IPAddress=^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$
#Validator.URL=^(?:ht|f)tp(s?+)\\:\\/\\/[0-9a-zA-Z](?:[-.\\w]*[0-9a-zA-Z])*(?::(?:0-9)*)*(?:\\/?+)(?:[a-zA-Z0-9\\-\\.\\?\\,\\:\\'\\/\\\\\\+=&%\\$#_]*)?+$
Validator.URL=^(?:ht|f)tp(?:s?)(?:[:A-Za-z0-9%/#?&.=-]*)$
Validator.CreditCard=^(\\d{4}[- ]?){3}\\d{4}$
Validator.SSN=^(?!000)([0-6]\\d{2}|7([0-6]\\d|7[012]))([ -]?)(?!00)\\d\\d\\3(?!0000)\\d{4}$
