Hi I've been running after a problem on my iOS app, I'm creating hundreds of keypairs with SecKeyCreateRandomKey for several different usernames, in this case, different identifiers kSecAttrApplicationTag. After I create the key pairs I extract the public keys using SecItemCopyMatching, again, hundreds of them. Problem is, without a logic explanation, some of those keys cannot be extracted. After running after the issue for hours, I noticed that EVERY time I try to extract a public key and the identifier have exactly 87 chars, the public key cannot be found. Doesn't matter the content or names used on the identifier, every time the length hits 87, SecItemCopyMatching returns -25300 is this some kind of limitation that is not explained on the documentation? thanks digging deeply I noticed several identifier sizes fail to extract the key: [982:69528] key with 7 chars is invalid [982:69528] key with 23 chars is invalid [982:69528] key with 39 chars is invalid [982:69528] key with 55 chars is invalid [982:69528] key with 71 chars is invalid [982:69528] key with 87 chars is invalid [982:69528] key with 103 chars is invalid [982:69528] key with 119 chars is invalid [982:69528] key with 135 chars is invalid [982:69528] key with 151 chars is invalid [982:69528] key with 167 chars is invalid [982:69528] key with 183 chars is invalid [982:69528] key with 199 chars is invalid [982:69528] key with 215 chars is invalid [982:69528] key with 231 chars is invalid [982:69528] key with 247 chars is invalid [982:69528] key with 263 chars is invalid [982:69528] key with 279 chars is invalid [982:69528] key with 295 chars is invalid
