Function Documentation

rpmRC headerCheck ( pgpDig  dig,
const void *  uh,
size_t  uc,
const char **  msg 
)

Check header consistency, performing headerGetEntry() the hard way.

Sanity checks on the header are performed while looking for a header-only digest or signature to verify the blob. If found, the digest or signature is verified.

Parameters:
dig signature parameters container
uh unloaded header blob
uc no. of bytes in blob (or 0 to disable)
Return values:
*msg verification error message (or NULL)
Returns:
RPMRC_OK on success

Check header consistency, performing headerGetEntry() the hard way.

Sanity checks on the header are performed while looking for a header-only digest or signature to verify the blob. If found, the digest or signature is verified.

Parameters:
ts transaction set
uh unloaded header blob
uc no. of bytes in blob (or 0 to disable)
Return values:
*msg signature verification msg
Returns:
RPMRC_OK/RPMRC_NOTFOUND/RPMRC_FAIL
