in reply to ecc_encrypt $message clear text is limited in length

Well I don't see many other folks commenting on this but recognize that this same challenge may be presented to other folks moving from RSA to ECC. My latest thought is that what I am experiencing is similar to maximum clear text length available for encryption in RSA being defined by key length. So, in RSA a 2048 bit length key will provide for a clear text length (string) of just under 256 bytes. So, my error, it appears, was in thinking that I could encrypt the entirety of a long string via ECC but in reality I need to leverage a symmetric (like AES) solution to encrypt the larger string and then ECC to encrypt the password.

Obviously, elliptical curve cryptography is not my day job. :-) Feel free to provide clarity to the nonsense that I have described.
