Message Protection

Provide cryptographic protection to secure message integrity.

Topics

Message Wrapping and Verification

Apply a Message Integrity Code (MIC) to a message to guarantee its integrity. Ensure confidentiality using encryption and decryption.

gss_get_mic

Returns a token that contains the MIC for a message.

gss_verify_mic

Returns an indication of whether the integrity of a message is intact, given its MIC token.

gss_wrap

Returns a secure message created by calculating and attaching a MIC to the input message, and then optionally encrypting it.

gss_unwrap

Returns the original version of a secure message by optionally decrypting it and then extracting and verifying the attached MIC.

gss_sign

Returns a digital signature for a message.

Deprecated
gss_verify

Returns a flag that indicates the integrity of a message’s digital signature.

Deprecated
gss_seal

Returns a secure message created by calculating and attaching a MIC to the input message, and then optionally encrypting it.

Deprecated
gss_unseal

Returns the original version of a secure message by optionally decrypting it and then extracting and verifying the attached MIC.
