+MCPB uses PKCS#7 (Cryptographic Message Syntax) for digital signatures:
 
 - Signatures are stored in DER-encoded PKCS#7 SignedData format
-- The signature is appended to the DXT file with markers (`DXT_SIG_V1` and `DXT_SIG_END`)
-- The entire DXT content (excluding the signature block) is signed
+- The signature is appended to the MCPB file with markers (`MCPB_SIG_V1` and `MCPB_SIG_END`)
+- The entire MCPB content (excluding the signature block) is signed
 - Detached signature format - the original ZIP content remains unmodified
