pdf-encryption-level

This single-valued attribute specifies the level of encryption used to encrypt PDF documents. A high level of encryption provides enhanced security. However, some users might not be able to open PDF documents that use a high level of encryption.

Allowed values

You can enter one of these fixed values:

bits40

A low level of encryption (a 40-bit encryption key) is used. Select this value if you send PDF documents in an email to countries that do not use 128-bit encryption, or for Adobe Reader 3.0 - 4.x.

bits128

A high level of encryption (a 128-bit encryption key) is used. Select this value for sensitive PDF documents.

Default value
