Microsoft Security Utilities - Secret Masker

microsoft-security-utilities-secret-masker is part of the Microsoft Security Utilities used internally. You can find the related .NET SDK package here. This Secret Masker Python library focuses on:

• providing some built-in detection rules in json format

• detecting sensitive data for given input

• masking sensitive data with simple symbols or sha256 hash for given input

Installation

You can install the package via pip:

pip install microsoft-security-utilities-secret-masker

Usage

You can use the SecretMasker class to detect and mask sensitive data in your input. Here is an example:

from microsoft_security_utilities_secret_masker import SecretMasker, load_regex_patterns_from_json_file

# Load built-in detection rules
precisely_classified_regex_patterns = load_regex_patterns_from_json_file('PreciselyClassifiedSecurityKeys.json')
unclassified_regex_patterns = load_regex_patterns_from_json_file('UnclassifiedPotentialSecurityKeys.json')
# construct secret masker with chosen patterns
regex_patterns = precisely_classified_regex_patterns.union(unclassified_regex_patterns)
secret_masker = SecretMasker(regex_patterns)

input = "This is a sample input with no secrets"
detected_secrets = secret_masker.detect_secrets(input)
processed_input = secret_masker.mask_secrets(input)
