I want to listen to my voicemails in a secure but convenient fashion. I plan do this by having my PBX encrypt the voicemail using openssl aes 256 cbc with salt and a single static password. The voicemail would be emailed to my Gmail address where I am creating an chrome app to decrypt it using the established static password and play it.
What are the security implications of establishing such a system or is there a better recommended encryption setup? Also, as a side note, would this setup be considered HIPAA compliant?
