Numbers given are max size in bits.

Examples:
 
2048 = generate & use up to 2048 bits

[2048] = encrypt up to 2048 bits, but not decrypt

 
X = full use, incl. new keys
( x ) = use, but not on new keys

Note that RSAv3 keys do not include symmetric cipher preferences. PGP defaults to IDEA when using RSAv3 keys.

 
X = full use, incl. new keys
( x ) = use, but not on new keys

Note that PGP does not append  message digest algorithm preferences on the keys it creates. PGP defaults to MD5 for RSAv3 keys and SHA1 for DH/DSS keys. For RSAv4 keys, PGP 7.0.x versions use MD5, while the newer 7.1.x versions use SHA1.

 
X = full use, incl. new keys

Note that PGP does not append compression algorithm preferences on the keys it creates. PGP defaults to ZIP.

 
The 9x/Me, NT4, & Win2K columns give the max size in gb of container volumes when those volumes are formated FAT16/FAT32/NTFS respectively.

Examples:

2/4/---: FAT16 max is 2gb, FAT32 max is 4gb, NTFS is not supported.
 
4/32/u
: FAT16 max is 4gb, FAT32 max is 32gb, NTFS max is unknown/unlimited.

Note that the file system of the host drive will also constrain the allowed max size of a PGPdisk volume. Generally speaking, NTFS host drives will allow larger PGPdisk volumes. On PGP 8.0, FAT16/32 host drives limit the max volume size to 4gb on WinNT4 & Win2K; on Win9x/Me, FAT16 host drives limit volume size to 2gb and FAT32 host drives limit volume size to 4gb. For more detailed info on PGPdisk Volume Sizes, see THIS page.

Note that PGPdisk from PGP 8.0 builds will automatically upgrade existing PGPdisk volumes from PGP 6.5.x, 6.0.x, and PGPdisk 1.0 to the new PGPdisk format used by PGP 8.0.

(2048) = use up to 2048 bits, but not generate
[2048] = encrypt up to 2048 bits, but not decrypt

* PGP 2.6.2 contains a bug that causes PGP to generate 2047 bit RSAv3 keys even when 2048 bit keys (the max) are requested. It can use true 2048 bit RSAv3 keys generated by other versions of PGP.

Note that RSAv3 keys do not include symmetric cipher preferences. PGP defaults to IDEA when using RSAv3 keys.

Note that PGP does not append  message digest algorithm preferences on the keys it creates. PGP defaults to MD5 for RSAv3 keys and SHA1 for DH/DSS keys. For RSAv4 keys, PGP 7.0.x versions use MD5, while the newer 7.1.x versions use SHA1.

For RSAv4 keys, PGP 7.0.x versions use MD5, while the newer 7.1.x versions use SHA1. Interestingly, the PGP 6.5.8ckt versions allow users to specify their own message digest algorithm preferences (while official versions of PGP do not).

The 9x/Me, NT4, & Win2K columns give the max size in gb of container volumes when those volumes are formated FAT16/FAT32/NTFS respectively.

Examples:

2/4/---: FAT16 max is 2gb, FAT32 max is 4gb, NTFS is not supported.
 
4/32/u
: FAT16 max is 4gb, FAT32 max is 32gb, NTFS max is unknown/unlimited.

Note that the file system of the host drive will also constrain the allowed max size of a PGPdisk volume. Generally speaking, NTFS host drives will allow larger PGPdisk volumes. On PGP 6.5.8ckt, FAT16/32 host drives limit the max volume size to 4gb on WinNT4 & Win2K; on Win9x/Me, FAT16/32 host drives limit volume size to 2gb. For more detailed info on PGPdisk Volume Sizes, see THIS page.

Note that while most versions of GPG will at least use RSAv3 keys, the IDEA extension must be loaded in order for GPG to be fully PGP 2.x compatible (PGP defaults to IDEA as the symmetric cipher for RSAv3 keys, the only key type it uses). ** GPG 1.0.4 and earlier will not load the IDEA extension, thus nixing PGP 2.x compatibility.
