[[Category: Definition]]
To decrypt is to decode. In compliance with HIPAA regulations, the security of patient information must be maintained at all times. In cases where such information needs to be transmitted electronically, the security requirement is that such data should be coded at the source and sent as an encrypted message. When it gets to the recipient, it arrives as an encrypted message. To ensure that only the right person has access to the material, the message has to be decrypted, using secret passwords or key.

Decryption is the second part of the process to ensure that the data is now decoded (or unscrambled) into readable material and seen by the intended recipient.

“Decrypting is the act of translating a message written with 'secret characters' into a readable message (the unencrypted message). It is, by far, one of the most important areas in computer security, since modern encryption algorithms can ensure all three pillars of a secure conversation: privacy, integrity, and authentication.” (http://gdp.globus.org/gt4-tutorial/multiplehtml/ch09s02.html)

The method of decryption has to match the mode of encryption. That is, one key ‘locks’ at the sender’s end and another key ‘opens’ at the receiver end.  Some of the common methods are Public Key Encryption and Private Encryption. Also additional decryption keys can be designated in cases where the need to decrypt a message without having the initial secret keys.

“An Additional Decryption Key (ADK) is a powerful PGP keypair which allows an organization to decrypt emails, files, and PGPdisks which were encrypted to, or by, someone in the organization. When an ADK is enabled and enforced in an organization, encryption to a user's public key requires encryption to the ADK as well. This allows the owner(s) of the ADK to decrypt a given user's encrypted data without that user's authorization. This ensures that if an employee leaves the organization or must be monitored for any reason, their encrypted data may be decrypted using the ADK.” (https://pgp.custhelp.com/app/answers/detail/a_id/231/~/how-to%3A-designate-additional-decryption-key-(adk))
