Does slapt-get support the GPG/PGP signature verification?
Yes, as of 0.9.12 slapt-get can be built with gpgme support that allows slapt-get to verify the signature of the CHECKSUMS file on each mirror. This requires the presence of the signature file and the GPG-KEY file on the package source. The GPG-KEY is imported into the local keychain using the –add-keys option. When running –update, the signature file for the CHECKSUMS listing is downloaded and verification is attempted. If the key is not present slapt-get mentions this and continues on. slapt-get only halts if verification failed.
