the number of signatures is shown as a tooltip if you hover the mouse on the size column in key manager. a key has to be expanded once for this to work.

this function returns the maximum supported key size of the algorithm specified by the encryption descriptor td in bytes.
this function returns the maximum supported key size of the algorithm specified by the encryption descriptor td in bytes.

see also mcrypt_enc_get_supported_key_sizes() which is used on open encryption modules.

the example below implements a filter named rot13 on the foo-bar.txt stream which will perform rot-13 encryption on all letter characters written to/read from that stream.
this method is called upon filter shutdown (typically, this is also during stream shutdown), and is executed after the flush method is called.

openssl_sign() computes a signature for the specified data by using sha1 for hashing followed by encryption using the private key associated with priv_key_id. note that the data itself is not encrypted.
