Decryption of Sys_property failing.

[andinh-vu]

Hi Team,

I am trying to testing why the decrpytion of a password is failing.

I have a field in the sys_properties set as password2 for security purposes.

As per article below.

https://docs.servicenow.com/bundle/jakarta-servicenow-platform/page/administer/encryption/task/t_Enc...

and this is the snip of code i have taken from the script include that decrypts it for rest messages.

which i have modified to test using background script.

Var userPass = "encrypted Sys_property";           // Decrypt password     var Encrypter = new GlideEncrypter();       var encrText = userPass; // current.<<your field name>>       var decrText = Encrypter.decrypt(encrText); gs.print(encrText); gs.print(decrText);

the two fields i have printed show exactly the same value and i get this error at the top of the background script.

Input length must be multiple of 8 when decrypting with padded cipher


any ideas why it seems like its no working?

Well this is sad,

it seems the encrypted password was encrypted twice over and broke.

hi Thai-An,

I think GlideEncrypter is to decrypt field/column value stored as "password2" type while sys_properties encrypted value are not stored as this type.

Instead, use "gs.getProperty('property_name')" to get the clear text value.

useful reference for forms contain password2 fields:

hope this helps.
