Concerning the Rite: The Reconciliation of a Penitent (BCP 447)
The ministry of reconciliation, which has been committed by Christ to his Church, is exercised through the care each Christian has for others, through the common prayer of Christians assembled for public worship, and through the priesthood of the Church and its ministers declaring absolution.
The Reconciliation of a Penitent is available for all who desire it. It is not restricted to times of sickness. Confessions may be heard anytime and anywhere.
Two equivalent forms of service are provided here to meet the needs of penitents. The absolution in these services may be pronounced only by a bishop or priest. Another Christian may be asked to hear a confession, but it must be made clear to the penitent that absolution will not be pronounced; instead, a declaration of forgiveness is provided. When a confession is heard in a church building, the confessor may sit inside the altar rails or in a place set aside to give greater privacy, and the penitent kneels nearby. If preferred, the confessor and penitent may sit face to face for a spiritual conference leading to absolution or a
declaration of forgiveness.
When the penitent has confessed all serious sins troubling the conscience and has given evidence of due contrition, the priest gives such counsel and encouragement as are needed and pronounces absolution. Before giving absolution, the priest may assign to the penitent a psalm, prayer, or hymn to be said, or something to be done, as a sign of penitence and act of thanksgiving.
The content of a confession is not normally a matter of subsequent discussion. The secrecy of a confession is morally absolute for the confessor, and must under no circumstances be broken.

From Father Rick+, I will not know your identity unless you ask me to turn and speak with you.  I will be extremely careful to avoid any actions which might allow me to know who you are.  Please do not be offended if I do not turn around and acknowledge you, even if you make loud noises when entering the chapel.  My not turning is extremely intentional and I will leave the chapel for a few moments before returning to put out the candles.  In this way, even if you remain, I will not know if you stepped in while I was walking out for a moment.  I believe in an absolute seal of all things said in confession and would go to jail or renounce my orders to keep that seal intact. (Of course, I also rely on Holy Forgetfulness, for which I pray before & after every confession).
