Spring Boot JASYPT Failure Failed to bind properties under 'spring.datasource.password' - spring-boot

Question

We currently have JASYPT running in boot 2.2.4, jasypt 3.0.2 with not issues. Only exception is the jasypt passphrase is obtained from a DB from a postProcessEnvironment event.
The new Spring Boot 2.3.2, Jaspt 3.0.2 throws the following on startup.

I do not have a custom Encryptor bean
Application starts with non-encrypted password.
TRIED:
iv-generator-classname: org.jasypt.NoIvGenerator
iv-generator-classname: org.jasypt.RandomIvGenerator
If I down grade JASYPT to 2.1.2 the application starts.

Answer 1

According to their release notes default encryption algorithm has been changed in 3.0.0 so what they suggest is to set these:
jasypt:
encryptor:
algorithm: PBEWithMD5AndDES
iv-generator-classname: org.jasypt.iv.NoIvGenerator

Answer 2

This answer is irrelavant of version, if your jasypt.encryptor.password is not the password that you used to encrypt your passwords, then it would fail also because it cant decrypt.
