Computing Dictionary
 
 Definition: 

1. A value used to identify a record in a database, derived by applying some fixed function to the record. The key is often simply one of the fields (a column if the database is considered as a table with records being rows, see "key field"). Alternatively the key may be obtained by applying some function, e.g. a hash function, to one or more of the fields. The set of keys for all records forms an index. Multiple indexes may be built for one database depending on how it is to be searched.

2. A value which must be fed into the algorithm used to decode an encrypted message in order to reproduce the original plain text. Some encryption schemes use the same (secret) key to encrypt and decrypt a message, but public key encryption uses a "private" (secret) key and a "public" key which is known by all parties.

 
Dream Dictionary
 
 Definition: Seeing a key in your dream, symbolizes opportunities, access, control, secrets, or responsibilities. You may be locking away your own inner feelings and emotions. Dreaming that you lose your keys means your fear of losing your position or status in life. You may have lost control of yourself. It may also foretells of unexpected changes and unpleasant adventures. If you give your key away, then it suggests that you have given up control of some situation or responsibility. Dreaming that you find keys means that you have found a solution to a problem. Seeing broken keys in your dream means many quarrels and possibly a break-up. Hearing the sounds of keys rattling indicates that you have the right attitude toward life. You are heading in the right direction and asking all the right questions in the process. It is also a sign of decisive action.
 
Easton Bible Dictionary
 
 Definition: 

frequently mentioned in Scripture. It is called in Hebrew _maphteah_, i.e., the opener (Judg. 3:25); and in the Greek New Testament _kleis_, from its use in shutting (Matt. 16:19; Luke 11:52; Rev. 1:18, etc.). Figures of ancient Egyptian keys are frequently found on the monuments, also of Assyrian locks and keys of wood, and of a large size (comp. Isa. 22:22).

The word is used figuratively of power or authority or office (Isa. 22:22; Rev. 3:7; Rev. 1:8; comp. 9:1; 20:1; comp. also Matt. 16:19; 18:18). The "key of knowledge" (Luke 11:52; comp. Matt. 23:13) is the means of attaining the knowledge regarding the kingdom of God. The "power of the keys" is a phrase in general use to denote the extent of ecclesiastical authority.
