ejmask's Issues

Non String Values are not Masked

Issue Report

Using the JsonFieldPatternBuilder, the masker appears to only mask string values, while ignoring other non-string values (e.g. numbers, booleans, ...etc).

Expected Behavior

{"name": "omitted", "id": "omitted"}

Actual Behavior

{"name": "omitted", "id": 125}

Steps to Reproduce the Issue

Check the following piece of code:

class SampleJsonFilter: BaseFilter(JsonFieldPatternBuilder::class.java,  *maskedFields) {
    override fun getPatternBuilder(): Class<out IPatternBuilder> = JsonMaskPatternBuilder::class.java

    override fun getFieldNames(): Array<String> = arrayOf("name", "id")
}

fun main() {
    var masked = ""
    json = "{ \"name\": "Linux", \"id\": 125 }"
    val maskingConfig = JsonMaskingConfig.builder()
        .maskKeys(maskedFields.toSet())
        .maskStringsWith("omitted")
        .build()

    val masker = JsonMasker.getMasker(maskingConfig)
    EJMaskInitializer.addFilter(SampleJsonFilter())
}

Will pattern based or position based masking be supported?

We'd like to have masking methods to mask sensitive data in random file formats such as TXT or CSV files.
