src/main/resources/validation.properties

# 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}$
# Validator.password_cap=((?=.*\\d)(?=.*[a-z])(?=.*[A-Z]).{8,20})
Validator.SafeString=^[.;:,=\\*\/\/_()\\-0-9\\p{L}\\p{Space}]{0,1024}$
Validator.email=^[A-Za-z0-9._%'-]+@[A-Za-z0-9.-]+\\.[a-zA-Z]{2,4}$
Validator.ipddress=^(?:(?: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.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}$

# as used by apache commons validator for strings
# Validator.string=^[\\.;:,\\=&\\*\\/\\/_()\\[\\]@\\|\\-0-9\\p{L}\\p{Space}]{0,1024}$
