Hi All,

I wanted to toss the following out in case others grepped for it on
the group. I know Wei had addressed it previously.

PSSR does not appear to be a viable solution for _hand keying_ a
Signature with Recovery (an example application would be a product
key). The ciphertext appears to be too large.

Security levels not withstanding, here are some figures and results

256 bit curve:
 PK_Signer: key too short for this signature scheme
384 bit curve:
 Messages of 1 to 4 bytes: length of 54 bytes (approximately 85
Base32 Encoded digits)
 Message of 6 bytes: TF_SignerBase: the recoverable message part is
too long for the given key and algorithm
