Default WebFOCUS encryption.
AES (Advanced Encryption Standard) encryption.
You can enable alternate AES encryption providers in the Administration Console. The key length may be 128 bits, 192 bits, or 256 bits.
For information about configuring ReportCaster for AES encryption, see Using the Zip Encryption Protection Default Plug-in in the TIBCO WebFOCUS® ReportCaster Guide.
Note: Previous versions of WebFOCUS software supported custom security encryption providers based on custom algorithms. This feature has been deprecated in favor of AES encryption. If you require the use of a custom algorithm, consult Customer Support Services.
The encryption key information is stored in a plain text file and is represented by a sequence of characters in hexadecimal notation. Each eight bits of a key (or one byte) is represented by two hexadecimal characters. For example, a 64-bit (or 8-byte) key is represented by 16 hexadecimal characters. Each character is either a number (0-9) or a letter (A-F).
The following table specifies the number of hexadecimal characters required for encryption keys for the AES algorithm.
