Security Utility Project (in Kotlin)

I am looking for a developer to work on a security utility project in Kotlin.

Specific security features to be implemented in the project include:
- encryption
- decryption
- hashing

I do not have any existing security-related code that needs modifying, so we will start fresh.

Ideal skills and experience for this job include:
- Proficiency in Kotlin programming language
- Strong understanding of security concepts and encryption/decryption/encoding techniques
- Experience in developing secure software applications
- Knowledge of different access control mechanisms
